Tracheobronchial malacia and stenosis in children in intensive care: bronchograms help to predict oucome. (1/132)

BACKGROUND: Severe tracheobronchial malacia and stenosis are important causes of morbidity and mortality in children in intensive care, but little is known about how best to diagnose these conditions or determine their prognosis. METHODS: The records of all 62 children in whom one or both of these conditions had been diagnosed by contrast cinetracheobronchography in our intensive care unit in the period 1986-95 were studied. RESULTS: Seventy four per cent of the 62 children had congenital heart disease; none was a preterm baby with airways disease associated with prolonged ventilation. Fifteen of the children had airway stenosis without malacia; three died because of the stenosis and two died from other causes. Twenty eight of the 47 children with malacia died; only eight children survived without developmental or respiratory handicap. All children needing ventilation for malacia for longer than 14 consecutive days died if their bronchogram showed moderate or severe malacia of either main bronchus (15 cases), or malacia of any severity of both bronchi (three additional cases); all children needing ventilation for malacia for longer than 21 consecutive days died if their bronchogram showed malacia of any severity of the trachea or a main bronchus (three additional cases). These findings were strongly associated with a fatal outcome (p<0.00005); they were present in 21 children (all of whom died) and absent in 26 (of whom seven died, six from non-respiratory causes). They had a positive predictive value for death of 100%, but the lower limit of the 95% confidence interval was 83.9% so up to 16% of patients meeting the criteria might survive. CONCLUSION: In this series the findings on contrast cinetracheobronchography combined with the duration of ventilation provided a useful guide to the prognosis of children with tracheobronchomalacia. The information provided by bronchoscopy was less useful.  (+info)

Primary bronchomalacia and patent ductus arteriosus: simultaneous surgical correction in an infant. (2/132)

We report the clinical course of a 6-month-old girl with recurrent infection of the left lung, persistent wheezing, and a suspected congenital heart anomaly (patent ductus arteriosus. Chest radiography revealed hyperinflation and slight inflammation of the left lung. Tracheobronchoscopy and left-sided bronchography showed a collapsed segment of the left main bronchus, 3 cm long. Computed tomography confirmed hyperinflation of the left lung and atelectasis of the superior lobe. There were no signs of extramural compression. Color-flow Doppler echocardiography confirmed the suspicion of patent ductus arteriosus. To the best of our knowledge, there is no other report in the literature of a patient with this combination of anomalies. After receiving 2 weeks of antibiotic treatment, the patient underwent surgical repair The patent ductus arteriosus was closed by means of a triple-ligature procedure, and during the same operation a bronchopexy was performed, securing the left main bronchus to the closed ductus tissue by means of sutures. There have been no complications in the postoperative period. Clinical follow-up, as well as echocardiography and bronchoscopy, have yielded normal results 14 months after surgery.  (+info)

Bronchial atresia with transient spontaneous disappearance of a mucocele. (3/132)

We report the transient spontaneous disappearance of a mucocele due to bronchial atresia. Two years before presentation, a chest radiograph showed a hyperlucent right upper lung and a mucocele near the right hilum. A chest radiograph taken 1 year later showed that the mucocele had disappeared leaving an ovoid outline of a dilated bronchus. A chest radiograph obtained 3 months before presentation showed that the mucocele was present again. Atresia of the B3b bronchus of the right upper lobe was noted on thoracotomy. The "disappearance" of the mucocele probably was due to the clearance of mucoid material through collateral airways.  (+info)

Mucoid impaction caused by monokaryotic mycelium of Schizophyllum commune in association with bronchiectasis. (4/132)

A 51-year-old female was admitted to our hospital because of fever, cough, and hemoptysis. A chest radiograph showed a partial collapse of the left upper division and infected bullae in the left upper lobe. Bronchoscopic examination showed thick mucous plugs in the left upper bronchus. The isolates of the plugs proved to be Schizophyllum commune. Neither accumulation of eosinophils nor Charcot-Leyden crystals were present in the plugs. Mild ectatic changes of the left upper bronchus had been observed 17 years previously. We describe the first case of mucoid impaction, which was independent of the immunological reactions, caused by S. commune in association with bronchiectasis.  (+info)

Regenerative growth of respiratory bronchioles in dogs. (5/132)

Loss of lung units due to pneumonectomy stimulates growth of the remaining lung. It is generally believed that regenerative lung growth involves only alveoli but not airways, a dissociated response termed "dysanaptic growth." We examined the structural response of respiratory bronchioles in immature dogs raised to maturity after right pneumonectomy. In another group of adult dogs, we also examined the effect of preventing mediastinal shift after right pneumonectomy on the response of respiratory bronchioles. In immature dogs after pneumonectomy, the volume of the remaining lung increased twofold, with no change in volume density, numerical density, or mean diameter of respiratory bronchiole, compared with that in the control lung. The number of respiratory bronchiole segments and branch points increased proportionally with lung volume. In adult dogs after pneumonectomy, prevention of mediastinal shift reduced lung strain at a given airway pressure, but lung expansion and regenerative growth of respiratory bronchiole were not eliminated. We conclude that postpneumonectomy lung growth is associated with proliferation of intra-acinar airways. The proportional growth of acinar airways and alveoli should optimize gas exchange of the regenerated lung by enhancing gas conductance and mixing efficiency within the acinus.  (+info)

Tracheal size following tracheostomy with cuffed tracheostomy tubes: an experimental study. (6/132)

In view of the severe damage caused by unyielding, low residual volume cuffs, various modifications to the cuff of an intratracheal tube have been introduced. The merits of two low-pressure cuffs were assessed in an experimental study in dogs; both cuffs produced little visible damage to the tracheal wall in dogs intubated continuously over a two-week period. A modified technique of producing tantalum tracheobronchograms without distrubing the mucous blanket or traumatizing the tracheal wall is described. These tantalum radiological studies demonstrated a progressive temporary increase in size of the trachea at cuff level over the period of intubation with these cuffs. The implications of such a progressive weakness occurring in the tracheal muscle are discussed.  (+info)

Bronchial hysteresis in excised lungs. (7/132)

1. Intrapulmonary bronchi in excised dog lungs were outlined with tantalum dust and stereoscopic radiographs taken during deflation and inflation of the lung with air, saline, Ringer or EDTA solutions. Dimensions of airways as a percentage of their values at full inflation were calculated from measurements of the stereoscopic X-ray images. 2. The mean deflation-inflation diameter difference at a transpulmonary pressure of 5 cm H2O was 20% in the air-filled lung, 9% in the saline filled preparation and 2% after filling with EDTA in saline. 3. These results show that the intrapulmonary bronchi have an intrinsic hysteresis separate from the hysteresis imposed on them by the expansion of the surrounding parenchyma. This intrinsic hysteresis is mainly due to the tone of the smooth muscle in the bronchial wall.  (+info)

Local ablative procedures designed to destroy squamous-cell carcinoma. (8/132)

In a series of experiments in dogs, the bronchial mucosa was either excised or destroyed prior to closure of a bronchial stump following a lobectomy or the reanastomosis of a divided bronchus. The experiments were designed to simulate the clinical situation in which focal areas of squamous-cell carcinoma in situ in the bronchial margin would be managed by local ablation of the mucosa rather than by excision of additional bronchus. The experiments demonstrated that the bronchial mucosa is not necessary for bronchial healing. They also demonstrated that functionally and morphologically normal bronchial epithelium regenerates across the denuded bronchus. The source of this regenerated epithelium appears to be the submucosal glands which remain in the bronchial wall after a variety of local ablative procedures. Since our clinical experience has demonstrated that these submucosal glands frequently contain small foci of squamous-cell carcinoma in situ, we have concluded that either excision or thermal destruction of the bronchial mucosa has very limited clinical application and should be considered only in patients who cannot tolerate excision of more than one lobe of the lung.  (+info)

Bronchograms were made in eight men, chosen on clinical grounds as representative of three grades of severity in a series of 67 male bronchitis studied prospectively over a period of 10 years, with the object of ascertaining the anatomical condition at the end of this period. In the stationary group the bronchograms showed only a mild mucous reaction, and peripheral filling was generally good. In the slowly progressive group, mucous obstruction was evident and fairly widespread, and organic changes were present, though not widespread or severe. In the progressive group, both mucous obstruction and organic change were widespread. It was noted that when both mucous obstruction and organic changes were observed the upper lobes were seen to be relatively normal with the exception of the progressive cases in which all changes were more severe. The bronchographic abnormalities were found to be closely correlated with the grades of clinical severity.. ...
A bronchography is a radiographic (x-ray) examination of the interior passageways of the lower respiratory tract. The structures of the lower respiratory tract, which include the larynx (voice box), trachea (windpipe), and bronchi (larger branching airways to the lungs), become visible on x-ray film after contrast dye is instilled through either a catheter or bronchoscope (narrow, flexible, lighted tube) into these areas. Contrast dye is a substance that causes a particular organ, tissue, or structure to be more visible on x-ray or other diagnostic images.. The contrast dye is released as the catheter or bronchoscope is inserted through the nose or mouth and advanced down the throat into the trachea and bronchi. The contrast dye forms a coating on the lining of the interior walls of these structures, thus outlining their anatomy on x-ray. In addition, abnormalities such as tumors, cavities, cysts, and obstructions may be revealed.. As a result of improved computerized tomography (CT scan) and ...

N2 - Asthma is characterized by airway inflammation, bronchial hyperresponsiveness, and airway obstruction by bronchospasm and bronchial wall thickening due to smooth muscle hypertrophy. A rise in cytosolic free Ca2+ concentration ([Ca2+]cyt) may serve as a shared signal transduction element that causes bronchial constriction and bronchial wall thickening in asthma. In this study, we examined whether capacitative Ca2+ entry (CCE) induced by depletion of intracellular Ca2+ stores was involved in agonist-mediated bronchial constriction and bronchial smooth muscle cell (BSMC) proliferation. In isolated bronchial rings, acetylcholine (ACh) induced a transient contraction in the ...

Diffuse patchy alveolar infiltrates are seen throughout both hemithoraces. The pattern is present in all lung lobes with many indistinct air bronchograms. The pulmonary vasculature is poorly visualized; however, the cardiovascular structures appear to be within normal limits. An endotracheal tube is present within the trachea to the level of the carina. An esophageal feeding tube is also seen extending to the level 3rd ribs before folding back on itself on the initial lateral projections. A final left lateral projection reveals the esophageal tube passing through the length of the esophagus and into the gastric fundus where it again curves backwards but remains within the gastric lumen. A few anomalous vertebrae are present within the thoracic spine and are likely within normal limits given the breed of the patient ...
X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film. X-rays are made by using external radiation to produce images of the body, its organs and other internal structures for diagnostic purposes. X-rays pass through body tissues onto specially treated plates (similar to camera film) and a negative type picture is made (the more solid a structure is, the whiter it appears on the film).. Depending on the results of the chest X-ray, additional tests or procedures may be requested by your doctor for further diagnostic information.. Other related procedures that may be used to diagnose problems of the chest and respiratory tract include chest fluoroscopy, chest ultrasound, computed tomography (CT scan) of the chest, lung biopsy, lung scans, mediastinoscopy, positron emission tomography (PET scan) of the chest, pleural biopsy, thoracentesis, sinus X-rays, pulmonary angiogram, bronchoscopy, and bronchography.

Objective: This study aimed to evaluate the normal range of quantitative CT in measuring the airway diameter at inspiration-expiration phase using 3D imaging in healthy adults. Materials and Methods: 68 healthy volunteers, including 42 males and 26 females, with the mean age of 49.3 (SD14.7) years, had undergone low-dose CT scan at full inspiration and the end of expiration. All CT scans were performed within the range from the lung apices to the diaphragm, at a tube potential of 120kVp and an effective mAs of 60. Afterwards, all CT images were analyzed using the 3D software (FUJIFILM Corporation SYNAPSE), and the airway tree was generated according to the automated region-growing technique, which was perpendicular to the cross section measurement of the segmental bronchus in bilateral lower lobes. Meanwhile, the imaging of segmental bronchus was classified as at inspiration and expiration phase in male group, and at inspiration and expiration phase in female group.

First, for model B and model C, Figure 5b,c shows that the decrease of t D (or the increase of t T ) causes the Fano antiresonances to shift to the Dirac point. In the opposite case, the Fano antiresonances on the two sides of the Dirac point will repel each other. Doxorubicin cell line For model D, the shift of Fano antiresonances. exhibits different results. We see that the decrease of t D (or the increase of t T ) causes the Fano antiresonances to shift right, whereas the Fano antiresonances shift left under the opposite situation. Albeit the shift of conductance spectra, the conductance properties can not be basically modified. Figure 5 The effect of the change of t d and t T on the AGNR conductance.

The trachea (windpipe) divides into two main bronchi (also mainstem bronchi), the left and the right, at the level of the sternal angle. The right main bronchus is wider, shorter, and more vertical than the left main bronchus. The right main bronchus subdivides into three segmental bronchi while the left main bronchus divides into two. The lobar bronchi divide into tertiary bronchi. Each of the segmental bronchi supplies a bronchopulmonary segment. A bronchopulmonary segment is a division of a lung that is separated from the rest of the lung by a connective tissue septum. This property allows a bronchopulmonary segment to be surgically removed without affecting other segments. There are ten segments per lung, but due to anatomic development, several segmental bronchi in the left lung fuse, giving rise to eight. The segmental bronchi divide into many primary bronchioles which divide into terminal bronchioles, each of which then gives rise to several respiratory bronchioles, which go on to divide ...
RADIOLOGY: LUNG: Case# 14: BRONCHIAL CARCINOID. 17-year-old female with asthma who presented with opacified left hemithorax on chest x-ray. Bronchoscopy, with rigid bronchoscope, showed left main stem bronchial occlusion. There is complete atelectasis of the left lung. This is an obstructive type atelectasis with bronchially dilated fluid-filled bronchograms seen throughout the lungs. Fluid-filled bronchograms are seen to the level of the left main stem arising near the carina. A small to moderate size pleural effusion is seen surrounding the left lung. There has been shift of the mediastinum towards the left slightly. This is most evident on the lower mediastinum. There are no enlarged mediastinal lymph nodes identified. The right lung appears normal without any air space opacities or pleural abnormality. Bronchial carcinoid tumors are relatively rare, accounting for approximately 5% of primary lung tumors. They may range from low-grade malignant typical carcinoid, which has a 5-year survival rate

Left lateralt thoracic- and upper abdominal view. Interestingly enough the consolidation has changed. What we see now is an air bronchogram/hepatization of the lung which simply means that the lung takes on the appearance of a liver. The bronchi appear white. Causes may vary, but in short it implies lung consolidation or atelectasis. In contrast to chest x-ray, ultrasound can divided air bronchograms into either static with no movement in the bronchi or to dynamic with movement in the bronchi (see youtube). The dynamic form has a very high specificity and positiv predictive value for pneumonia. In our case the air bronchogram is static but the clinical scenario implies an infectious process.. ...
The subdivision of the lung is characterised by the branching of the bronchi: the bronchial tree. The main bronchi form the stem of the bronchial tree, which splits within the lung dichotomously. The right main bronchus is called bronchus principalis dexter, the left bronchus is called bronchus principalis sinister. The main bronchi are divided into lobar bronchi - right in three lobar bronchi: bronchi lobares superior, medius and inferior and left into the bronchi lobares superior and inferior. Thereafter, there follows further division into segmental bronchi - right 10, left 9 segmental bronchi. This is followed by subsegmental bronchi, the bronchioles and finally the bronchioli terminales. The conductive, air-transporting phase of the bronchial tree ends here. Thereafter follows the sectional formation, which serves for gas exchange and as the lung parenchyma in the narrow sense. These include the bronchioli respiratorii, the ductus alveolaris and sacculi alveolares. The respiratory ...
Radiography of the lungs allows you to exclude local and disseminated lesions of the lungs, to detect concomitant diseases. Usually, after 2-3 years of the course of obstructive bronchitis, an increase in the bronchial pattern, deformation of the roots of the lungs, and emphysema of the lungs are revealed. Therapeutic and diagnostic bronchoscopy for obstructive bronchitis allows you to examine the bronchial mucosa, collect sputum and bronchoalveolar lavage . In order to exclude bronchiectasis, bronchography may be required .. A necessary criterion for the diagnosis of obstructive bronchitis is the study of the function of external respiration. The data of spirometry (including with inhalation tests), peak flowmetry , pneumotachometry are of the greatest importance . Based on the data obtained, the presence, degree and reversibility of bronchial obstruction, impaired pulmonary ventilation, stage of chronic obstructive bronchitis are determined.. The complex of laboratory diagnostics examines ...

A five month-old infant with congenital lobar emphysema is presented. Due to previously suspected diaphragmal hernia the infant underwent the surgery. Clinically, disorder was manifested with mild to severe respiratory symptoms. The indication for surgery was based on the radiological finding (hyperinflation of right upper lobe , as well as the computed tomography (herniation of the right lung to the left), lung scintigraphy (impaired perfusion of the right lung), bronchoscopy and bronchography the surgery, respectively. After lobectomy of upper right lobe the diagnosis was confirmed histopathologically as well ...

The patient was admitted for pneumonia to the medical service and provided with intravenous antibiotics. The patient was admitted to the medical service and provided with intravenous antibiotics. Blood cultures grew Streptococcus gordonii. A transthoracic echocardiogram demonstrated the presence of a tricuspid vegetation. She was presumed to have both a community-acquired pneumonia (CAP) and long-standing endocarditis. Pneumonia remains a common cause of death in the United States and is associated with considerable morbidity and mortality, particularly in elderly and immunocompromised patients. Common causes of pneumonia include Streptococcus pneumoniae and respiratory viruses.1 A growing body of literature demonstrates the superiority of thoracic ultrasound over plain radiography in the identification of pneumonia. Classic ultrasound findings of pneumonia include air or fluid bronchograms, focal B-lines, pleural effusions, and sub-pleural consolidations.2 These unique findings were recognized ...

We present an analysis of 400 intralobar and 133 extralobar sequestrations, six cases presenting intra- and extralobar sequestration simultaneously, five sequestrations of one whole lung, and two bilateral intralobar sequestrations.. This anomaly comprises 0·15-6·4% of all congenital pulmonary malformations. Usually the posterior basal segment is affected.. The aberrant artery in intralobar sequestration originated in 74% of all cases from the thoracic aorta, and in 14·8% there was more than one anomalous artery. The mean diameter of the aberrant arteries was 6·3-6·6 mm. Usually arteries with predominantly elastic fibres were found. Arteriosclerotic changes were common, even in children.. The venous return of the intralobar sequestration is, in 95·7% of all cases, via the pulmonary veins.. In 13·7% of all cases other congenital malformations were observed. Symptoms arose within the first decade of life in 37·2%. Bronchography and retrograde arteriography are the mainstay of diagnosis. ...
Airway wall thickening with bilateral pleural plaques seen in the lateral aspects of both lung fields on AP view. No interstitial disease is noted.
At each division point or generation, one airway branches into two or more smaller airways. The human respiratory tree may consist on average of 23 generations, while the respiratory tree of the mouse has up to 13 generations. Proximal divisions (those closest to the top of the tree, such as the bronchi) mainly function to transmit air to the lower airways. Later divisions including the respiratory bronchiole, alveolar ducts and alveoli, are specialized for gas exchange. The trachea is the largest tube in the respiratory tract and consists of tracheal rings of hyaline cartilage. It branches off into two bronchial tubes, a left and a right main bronchus. The bronchi branch off into smaller sections inside the lungs, called bronchioles. These bronchioles give rise to the air sacs in the lungs called the alveoli.[8] The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer ...
What are the symptoms of COPD? The two main symptoms are cough and breathlessness. COPD sufferers commonly complain about breathlessness and cough that develop gradually over a long period of time. The cough that COPD sufferer gets are usually productive which means they commonly cough up phlegm. The cough usually comes and goes initially but tends to become persistent as time passes. Breathlessness is usually intermittent and only occurs with exertion in the beginning, however if you continue to smoke, the breathlessness persists even when you are at rest, this can be quite distressing! Other symptoms are chronic sputum production, where you constantly cough up phlegm all day and recurrent chest infection. People with COPD are more prone to chest infection for obvious reasons, as the lining in the lung looses its normal defense mechanism against intruding bugs ...

An increased frequency of bacterial pneumonia occurs in HIV-infected individuals: however the development of bronchiectasis is not well recognized. We describe seven patients with HIV infection who developed chronic symptomatic lung disease, six with troublesome recurrent infective exacerbations. Bronchiectasis was demonstrated by computed tomography in five patients, and bronchial wall thickening was shown in a further two patients. The characteristics of the patients are described, and possible aetiological factors are discussed. As measures become available which prolong the later stages of HIV disease, bronchiectasis may become an increasing problem in this patient population. Early recognition and appropriate management may significantly alter morbidity in advanced HIV disease.

Repetitive imaging is required in cystic fibrosis (CF) lung disease in order to provide detailed information on regional distribution for severity assessment and therapy monitoring in clinical routine as well as interventional trials. CT has long overtaken the use of chest radiography because it provides higher morphological detail with respect to airway and parenchymal changes. This is closely linked to an increase in radiation exposure in CF individuals, who are referred for imaging procedures from a critically susceptible young age and may accumulate relevant doses during their lifetime. MRI, as an ionising radiation-free cross-sectional imaging modality, has taken the first step into the clinical arena in CF. MRI can depict the morphological hallmarks of CF lung disease such as bronchial wall thickening, bronchiectasis, mucus plugging, small airways disease and infiltrates at lower spatial resolution compared to CT but excels due to enhanced tissue characterisation and comprehensive ...

There is enormous physiological growth during infancy and childhood. Substantial differences were noted in the nose-throat morphology among the 5 subjects of different ages. These differences manifest themselves not only in airway dimension but also in airway morphology. For example, the nasal-laryngeal airway volumes of the 10-day-old, 7-month-old, 3-year-old, and 5-year-old were 6.4%, 18.8%, 24.2%, and 40.3% that of the 53-year-old, respectively. The 4 young subjects have smaller nostrils, a shorter turbinate region, and a narrower nasopharynx. The results of this study suggest that the nasal valve and vestibule region mature between the ages 3 and 5. This is supported by the much shorter nostril-valve distance and much smaller cross-sectional area of the nasal valve in the 2 infants, compared to the 2 older children, as well as the proximity of the these 2 parameters between the adult and the 2 older children (see Fig. 3A). Specifically, the nostril-valve distances are 8.0-11.2 mm for the 2 ...

Lung cancer is most commonly found in the epithelial cells of the major and segmental bronchi, and much rarer in the small or peripheral bronchi. It covers a group of tumors that originate from various tissues in the lungs. Such a tumor grows slowly, often without symptoms, blurry. It quickly spreads to other organs, while the results and progress of treatment are very small. However, the main cause of lung cancer is smoking, but others include airpolution, exposure to asbestos, ionizing radiation, nickel, chrome and arsenic, as well as passive smoking. When treating lung cancer, he most important fact is find it on time, or timely diagnosis. Various methods, invasive and noninvasive, include anamnesis, physical examination of the patient. Laboratory treatment, tumor markers, cytological analysis, bronchoscopy and cytopathological analysis. In assessing how much the disease is spread and affected, X-ray of the heart and lungs, CT of thorax, abdomen and brain, as well as bone scintigraphy are ...

We have developed an integrated in vitro and in silico framework to model the acute effects of BT on ASM and epithelial cells. In this framework, the in silico mathematical model serves as a bridge between the in vitro and in vivo thermal effects, which are inaccessible by other means. The in vitro model identified a sharp threshold in the response of both hBEC and ASM cells to heating. In vitro hBEC and ASM cell number decreased significantly after the addition of media heated to ≥65°C. Importantly, taking into account the heat loss over 10 s in the in vitro experiments, these cells were exposed to a mean temperature of 58-59°C. The mathematical model predicted a localised and highly heterogeneous heating pattern that is very sensitive to airway calibre, with a relatively small fraction of the bronchial wall heated to ,60°C in all but the smallest airways (see also [25]). The integrated in vitro and in silico model predictions were tested against in vivo bronchial biopsies taken pre- and ...

Röntgen discovered X-rays' medical use when he made a picture of his wife's hand on a photographic plate formed due to X-rays. The photograph of his wife's hand was the first ever photograph of a human body part using X-rays. When she saw the picture, she said, "I have seen my death."[28] The first use of X-rays under clinical conditions was by John Hall-Edwards in Birmingham, England on 11 January 1896, when he radiographed a needle stuck in the hand of an associate. On 14 February 1896, Hall-Edwards also became the first to use X-rays in a surgical operation.[29] The United States saw its first medical X-ray obtained using a discharge tube of Ivan Pulyui's design. In January 1896, on reading of Röntgen's discovery, Frank Austin of Dartmouth College tested all of the discharge tubes in the physics laboratory and found that only the Pulyui tube produced X-rays. This was a result of Pulyui's inclusion of an oblique "target" of mica, used for holding samples of fluorescent material, within the ...

... or hepatobiliary scintigraphy is scintigraphy of the hepatobiliary tract, including the gallbladder and bile ducts. The image produced by this type of medical imaging, called a cholescintigram, is also known by other names depending on which radiotracer is used, such as HIDA scan, PIPIDA scan, DISIDA scan, or BrIDA scan. Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and biliary system. A radioactive tracer is injected through any accessible vein and then allowed to circulate to the liver, where it is excreted into the bile ducts and stored by the gallbladder[1] until released into the duodenum. In the absence of gallbladder disease, the gallbladder is visualized within 1 hour of the injection of the radioactive tracer. If the gallbladder is not visualized within 4 hours after the injection, this indicates either cholecystitis or cystic duct obstruction, such as by cholelithiasis (gallstone formation).[2] This ...
The procedure involves the insertion of a Foley catheter into the distal urethra and minimally inflating it. This is followed by instillation of 30mL of water-soluble contrast and a plain radiograph is obtained; leakage of the contrast suggests urethral injury (usually secondary to pelvic trauma) and is an indication for surgical intervention. It is used when there is suspicion of urethral trauma, such as a history of trauma to the area followed by pain, inability to void urine, or the presence of blood at the urethral meatus, a scrotal hematoma, or free-floating prostate on rectal examination. If a urethral injury is suspected, a retrograde urethrogram should be performed before attempting to place a Foley catheter into the bladder. If there is a urethral disruption, a suprapubic catheter should be placed. ...
Four types of confocal microscopes are commercially available: Confocal laser scanning microscopes use multiple mirrors (typically 2 or 3 scanning linearly along the x and the y axis) to scan the laser across the sample and "descan" the image across a fixed pinhole and detector.. Spinning-disk (Nipkow disk) confocal microscopes use a series of moving pinholes on a disc to scan spots of light. Since a series of pinholes scans an area in parallel each pinhole is allowed to hover over a specific area for a longer amount of time thereby reducing the excitation energy needed to illuminate a sample when compared to laser scanning microscopes. Decreased excitation energy reduces photo-toxicity and photo-bleaching of a sample often making it the preferred system for imaging live cells or organisms.. Microlens enhanced or dual spinning disk confocal microscopes work under the same principles as spinning-disk confocal microscopes except a second spinning disk containing micro-lenses is placed before the ...

An upper gastrointestinal series, also called an upper gastrointestinal study or contrast radiography of the upper gastrointestinal tract, is a series of radiographs used to examine the gastrointestinal tract for abnormalities. A contrast medium, usually a radiocontrast agent such as barium sulfate mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are used to create radiographs of the regions of interest. The barium enhances the visibility of the relevant parts of the gastrointestinal tract by coating the inside wall of the tract and appearing white on the film. This in combination with other plain radiographs allows for the imaging of parts of the upper gastrointestinal tract such as the pharynx, larynx, esophagus, stomach, and small intestine such that the inside wall lining, size, shape, contour, and patency are visible to the examiner. With fluoroscopy, it is also possible to visualize the functional movement of examined organs such as swallowing, ...
The scanner platform generates a 3 D volume of the subject's head every TR. This consists of an array of voxel intensity values, one value per voxel in the scan. The voxels are arranged one after the other, unfolding the three-dimensional structure into a single line. Several such volumes from a session are joined together to form a 4 D volume corresponding to a run, for the time period the subject stayed in the scanner without adjusting head position. This 4 D volume is the starting point for analysis. The first part of that analysis is preprocessing. The first step in preprocessing is conventionally slice timing correction. The MR scanner acquires different slices within a single brain volume at different times, and hence the slices represent brain activity at different timepoints. Since this complicates later analysis, a timing correction is applied to bring all slices to the same timepoint reference. This is done by assuming the timecourse of a voxel is smooth when plotted as a dotted line. ...
Scintillography is mainly used in scintillation cameras in experimental physics. For example, huge neutrino detection underground tanks filled with tetrachloroethylene are surrounded by arrays of photo detectors in order to capture the extremely rare event of a collision between the fluid's atoms and a neutrino. Another extensive use of scintillography is in medical imaging techniques which use gamma ray detectors called gamma cameras. Detectors coated with materials which scintillate when subjected to gamma rays are scanned with optical photon detectors and scintillation counters. The subjects are injected with special radionuclides which irradiate in the gamma range inside the region of interest, such as the heart or the brain. A special type of gamma camera is the SPECT (Single Photon Emission Computed Tomography). Another medical scintillography technique, the Positron-emission tomography (PET), which uses the scintillations provoked by electron-positron annihilation phenomena. ...
The raw data collected by a PET scanner are a list of 'coincidence events' representing near-simultaneous detection (typically, within a window of 6 to 12 nanoseconds of each other) of annihilation photons by a pair of detectors. Each coincidence event represents a line in space connecting the two detectors along which the positron emission occurred (i.e., the line of response (LOR)).. Analytical techniques, much like the reconstruction of computed tomography (CT) and single-photon emission computed tomography (SPECT) data, are commonly used, although the data set collected in PET is much poorer than CT, so reconstruction techniques are more difficult. Coincidence events can be grouped into projection images, called sinograms. The sinograms are sorted by the angle of each view and tilt (for 3D images). The sinogram images are analogous to the projections captured by computed tomography (CT) scanners, and can be reconstructed in a similar way. However, the statistics of the data are much worse ...
The radiation used in CT scans can damage body cells, including DNA molecules, which can lead to cancer.[12] According to the National Council on Radiation Protection and Measurements, between the 1980s and 2006, the use of CT scans has increased sixfold (+500%). The radiation doses received from CT scans is variable. Compared to the lowest dose x-ray techniques, CT scans can have 100 to 1,000 times higher dose than conventional X-rays.[45] However, a lumbar spine x-ray has a similar dose as a head CT.[46] Articles in the media often exaggerate the relative dose of CT by comparing the lowest-dose x-ray techniques (chest x-ray) with the highest-dose CT techniques. In general, the radiation dose associated with a routine abdominal CT has a radiation dose similar to 3 years average background radiation (from cosmic radiation).[47] Some experts note that CT scans are known to be "overused," and "there is distressingly little evidence of better health outcomes associated with the current high rate of ...
The WHO committee did not have enough data to create definitions for men or other ethnic groups.[5] Special considerations are involved in the use of DXA to assess bone mass in children. Specifically, comparing the bone mineral density of children to the reference data of adults (to calculate a T-score) will underestimate the BMD of children, because children have less bone mass than fully developed adults. This would lead to an over-diagnosis of osteopenia for children. To avoid an overestimation of bone mineral deficits, BMD scores are commonly compared to reference data for the same gender and age (by calculating a Z-score). Also, there are other variables in addition to age that are suggested to confound the interpretation of BMD as measured by DXA. One important confounding variable is bone size. DXA has been shown to overestimate the bone mineral density of taller subjects and underestimate the bone mineral density of smaller subjects. This error is due to the way by which DXA calculates ...
For flexible tomographic reconstruction, open source toolboxes are available, such as TomoPy[5], ODL or the ASTRA toolbox.[6][7] TomoPy is an open-source Python toolbox to perform tomographic data processing and image reconstruction tasks at the Advanced Photon Source at Argonne National Laboratory. TomoPy toolbox is specifically designed to be easy to use and deploy at a synchrotron facility beamline. It supports reading many common synchrotron data formats from disk through Scientific Data Exchange,[8] and includes several other processing algorithms commonly used for synchrotron data. TomoPy also includes several reconstruction algorithms, which can be run on multi-core workstations and large-scale computing facilities.[9] The ASTRA Toolbox is a MATLAB toolbox of high-performance GPU primitives for 2D and 3D tomography, from 2009-2014 developed by iMinds-Vision Lab, University of Antwerp and since 2014 jointly developed by iMinds-VisionLab, UAntwerpen and CWI, Amsterdam. The toolbox supports ...
In the average person, the diaphragm should be intersected by the 5th to 7th anterior ribs at the mid-clavicular line, and 9 to 10 posterior ribs should be viewable on a normal PA inspiratory film. An increase in the number of viewable ribs implies hyperinflation, as can occur, for example, with obstructive lung disease or foreign body aspiration. A decrease implies hypoventilation, as can occur with restrictive lung disease, pleural effusions or atelectasis. Underexpansion can also cause interstitial markings due to parenchymal crowding, which can mimic the appearance of interstitial lung disease. Enlargement of the right descending pulmonary artery can indirectly reflect changes of pulmonary hypertension, with a size greater than 16 mm abnormal in men and 15 mm in women.[6] Appropriate penetration of the film can be assessed by faint visualization of the thoracic spines and lung markings behind the heart. The right diaphragm is usually higher than the left, with the liver being situated ...

Partial Anomalous Pulmonary Venous Drainage by CMR. CMR examinations in children typically last 15 to 60 minutes. In order to avoid blurry images the child must remain very still during the examination. Different institutions have different protocols for pediatric CMR, but most children 7 years of age and older can cooperate sufficiently for a good quality examination. Providing an age-appropriate explanation of the procedure to the child in advance will increase the likelihood of a successful study. After proper safety screening, parents can be allowed into the MRI scanner room to help their child complete the examination. Some centers allow children to listen to music or watch movies through a specialized MRI-compatible audiovisual system to reduce anxiety and improve cooperation. However, the presence of a calm, encouraging, supportive parent generally produces better results in terms of pediatric cooperation than any distraction or entertainment strategy short of sedation. If the child ...
... (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Ultrasound contrast agents rely on the different ways in which sound waves are reflected from interfaces between substances. This may be the surface of a small air bubble or a more complex structure. Commercially available contrast media are gas-filled microbubbles that are administered intravenously to the systemic circulation. Microbubbles have a high degree of echogenicity (the ability of an object to reflect ultrasound waves). There is a great difference in echogenicity between the gas in the microbubbles and the soft tissue surroundings of the body. Thus, ultrasonic imaging using microbubble contrast agents enhances the ultrasound backscatter, (reflection) of the ultrasound waves, to produce a sonogram with increased contrast due to the high echogenicity difference. Contrast-enhanced ultrasound can be used to image blood perfusion in organs, measure blood flow rate in the ...
During virtual colonoscopy it is not possible to take tissue samples (biopsy) or remove polyps, so a conventional colonoscopy must be performed if abnormalities are found.[7] Also, VC does not show as much detail as a conventional colonoscopy, so polyps smaller than between 2 and 10 millimeters in diameter may not show up on the images.[8] Furthermore virtual colonoscopy performed with CT exposes the patient to ionizing radiation, on the order of a milligray.[9] Some research has demonstrated that ultra-low dose VC can be just as effective in demonstrating bowel disease due to the great difference in x-ray absorption between air and the tissue comprising the inner wall of the colon. Optical colonoscopy is taken as the "gold standard" for colorectal cancer screening by the vast majority of the medical and research communities. However, some radiologists recommend VC as a preferred approach to colorectal screening. Virtual colonoscopy is favored by some professionals because it permits complete ...
In diffusion weighted imaging (DWI), the intensity of each image element (voxel) reflects the best estimate of the rate of water diffusion at that location. Because the mobility of water is driven by thermal agitation and highly dependent on its cellular environment, the hypothesis behind DWI is that findings may indicate (early) pathologic change. For instance, DWI is more sensitive to early changes after a stroke than more traditional MRI measurements such as T1 or T2 relaxation rates. A variant of diffusion weighted imaging, diffusion spectrum imaging (DSI),[4] was used in deriving the Connectome data sets; DSI is a variant of diffusion-weighted imaging that is sensitive to intra-voxel heterogeneities in diffusion directions caused by crossing fiber tracts and thus allows more accurate mapping of axonal trajectories than other diffusion imaging approaches.[5] Diffusion-weighted images are very useful to diagnose vascular strokes in the brain. It is also used more and more in the staging of ...
Computed tomography operates by using an X-ray generator that rotates around the object; X-ray detectors are positioned on the opposite side of the circle from the X-ray source. A visual representation of the raw data obtained is called a sinogram, yet it is not sufficient for interpretation. Once the scan data has been acquired, the data must be processed using a form of tomographic reconstruction, which produces a series of cross-sectional images. Pixels in an image obtained by CT scanning are displayed in terms of relative radiodensity. The pixel itself is displayed according to the mean attenuation of the tissue(s) that it corresponds to on a scale from +3,071 (most attenuating) to −1,024 (least attenuating) on the Hounsfield scale. Pixel is a two dimensional unit based on the matrix size and the field of view. When the CT slice thickness is also factored in, the unit is known as a Voxel, which is a three-dimensional unit. The phenomenon that one part of the detector cannot differentiate ...
Conventional FTCD has limitations for the study of cerebral lateralization. For example, it may not differentiate the lateralising effects due to stimulus characteristics from those due to light responsiveness, and does not distinguish between flow signals emanating from cortical and subcortical branches of the cerebral arteries of the circle of Willis. Each basal cerebral artery of the circle of Willis gives origin to two different systems of secondary vessels. The shorter of these two is called the ganglionic system, and the vessels belonging to it supply the thalami and corpora striata; the longer is the cortical system, and its vessels ramify in the pia mater and supply the cortex and subjacent brain substance. Furthermore, the cortical branches are divisible into two classes: long and short. The long or medullary arteries pass through the grey substance and penetrate the subjacent white substance to the depth of 3-4 cm. The short vessels are confined to the cortex. Both cortical and ...
... , or impedance plethysmography (IPG), is a non-invasive medical test that measures small changes in electrical resistance of the chest, calf or other regions of the body. These measurements reflect blood volume changes, and can indirectly indicate the presence or absence of venous thrombosis. This procedure provides an alternative to venography, which is invasive and requires a great deal of skill to execute adequately and interpret accurately. For the chest, the technique was developed by NASA to measure the split second impedance changes within the chest, as the heart beats, to calculate both cardiac output and lung water content. This technique has progressed clinically (often now called BioZ, i.e. biologic impedance, as promoted by the leading manufacturer in the US) and allows low cost, non-invasive estimations of cardiac output and total peripheral resistance, using only 4 skin electrodes, oscillometric blood pressure measurement and lung water volumes with minimal ...
Bone densities are often given to patients as a T score or a Z score. A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower. A Z score is just a comparison of what a patient's bone mineral density is in comparison to the average bone mineral density of a male or female of their age and weight. The WHO committee did not have enough data to create definitions for men or other ethnic groups.[5] Special considerations are involved in the use of DXA to assess bone mass in children. Specifically, comparing the bone mineral density of children to the reference data of adults (to calculate a T-score) will underestimate the BMD of children, because children have less bone mass than fully developed adults. This would lead to an over-diagnosis of osteopenia for children. To avoid an overestimation of bone ...

Bronchograms were made in eight men, chosen on clinical grounds as representative of three grades of severity in a series of 67 male bronchitis studied prospectively over a period of 10 years, with the object of ascertaining the anatomical condition at the end of this period. In the stationary group the bronchograms showed only a mild mucous reaction, and peripheral filling was generally good. In the slowly progressive group, mucous obstruction was evident and fairly widespread, and organic changes were present, though not widespread or severe. In the progressive group, both mucous obstruction and organic change were widespread. It was noted that when both mucous obstruction and organic changes were observed the upper lobes were seen to be relatively normal with the exception of the progressive cases in which all changes were more severe. The bronchographic abnormalities were found to be closely correlated with the grades of clinical severity.. ...
