METHODS: Using data gathered from 14 institutions, we performed a retrospective cohort study of patients. RESULTS: Real-time ultrasonography was used in 33% of attempts (N = 1,146). The subclavian vein (64%) was accessed preferentially for first site insertion. Real-time ultrasonography was less likely to be used for subclavian vein (odds ratio = 0.002; P , .0001) and more likely to be used when coagulopathy (international normalized ratio ,1.5) was present (odds ratio = 11.1; P = .03). The rate of mechanical complications was 3.5%. Real-time ultrasonography use was associated with greater procedural success rates on first-site attempt, but also with a greater risk of hemothorax.. CONCLUSION: Pediatric surgeons access preferentially the subclavian vein for central venous access, yet are less likely to use real-time ultrasonography at this site. Real-time ultrasonography was superior to the landmark techniques for the first-site procedure success, yet was associated with greater rates of ...

We have shown previously that the physical properties of myocardium in dogs can be characterized with quantitative ultrasonic integrated backscatter and that interrogation of the tissue with ultrasound can delineate cardiac cycle-dependent changes in ultrasonic backscatter in normal tissue that disappear with ischemia and reappear with reperfusion if functional integrity is restorable. To determine whether this approach can be applied to man, we implemented an automatic gain compensation and continuous data acquisition system to characterize myocardium with quantitative ultrasonic backscatter and to detect cardiac cycle-dependent changes in real time. We developed a two-dimensional echocardiographic system with quantitative integrated backscatter imaging capabilities for use in human subjects that can automatically differentiate ultrasonic signals from blood as opposed to those obtained from tissue and adjust the slope of the gain compensation appropriately. Real-time images were formed from a ...

Architectural distortion is an important ultrasonographic indicator of breast cancer. However, it is difficult for clinicians to determine whether a given lesion is malignant because such distortions can be subtle in ultrasonographic images. In this paper, we report on a study to develop a computerized scheme for the histological classification of masses with architectural distortions as a differential diagnosis aid. Our database consisted of 72 ultrasonographic images obtained from 47 patients whose masses had architectural distortions. This included 51 malignant (35 invasive and 16 non-invasive carcinomas) and 21 benign masses. In the proposed method, the location of the masses and the area occupied by them were first determined by an experienced clinician. Fourteen objective features concerning masses with architectural distortions were then extracted automatically by taking into account subjective features commonly used by experienced clinicians to describe such masses. The k-nearest neighbors (k-NN

This monograph expands on the ultrasound exploration of the ocular globe (or, in other words, the human eye) with a review of the current knowledge about ocular ultrasound techniques and its indications in ophthalmic pathology. Ocular echography has only been recently studied in greater detail by ophthalmologists thanks to new imaging techniques such as optical coherence tomography [OCT] and scanning lasers, which have become the preference in ocular exploration, relegating ultrasound to cases with poor fundus visualization. New ultrasound equipment with multi-frequency linear probes between 15 to 18 MHz, also permits technicians to observe ocular structures with greater detail. A key aspect of ultrasound is its dynamic capability, which allows assessing the displacement of intraocular structures and their relation to the different eye layers. This is crucial in diagnosing retina pathologies that can affect the outcome of cataract surgery. Ocular echography is also an excellent option to ...

Peak ascending and descending aortic blood flow velocities were measured using continuous wave Doppler ultrasound velocimetry in 30 children with coarctation or recoarctation of the aorta and in 13 control subjects. The results were compared with the arm to leg systolic blood pressure difference. The peak flow velocities in the descending aorta were significantly higher in the patients than in the control subjects and there was a close correlation with the systolic blood pressure gradient. Since there was no overlap of flow velocities between the patients and the control subjects the Doppler technique enables coarctation confidently to be excluded as well as demonstrating its presence and severity. The method is simple, rapid, independent of the condition of the aortic valve, and is applicable to neonates in whom the diagnosis of coarctation may otherwise be difficult. In older children it is useful for detecting recoarctation and following its progress, particularly in patients in whom a ...
Continuous-wave Doppler signal intensity is commonly expected to reflect the severity of mitral regurgitation. Physical principles predict that alignment of the imaging beam, flow velocity, and turbulence can also be important or even dominant determinants of continuous-wave Doppler signal intensity. The reliability of tracking regurgitant severity with continuous-wave Doppler signal intensity was assessed in vitro with varying volume, velocity, turbulence, and beam alignment. The conditions wherein continuous-wave Doppler signal intensity increased with regurgitant volume were specific but poorly predictable combinations of orifice size, flow volume, and perfect beam alignment. Under other conditions flow velocity and turbulence effects dominated, and continuous-wave Doppler signal intensity did not reflect changing regurgitant volume. Continuous-wave Doppler signal intensity-based impressions of regurgitant severity may be unreliable and even misleading under some circumstances.. ...

Ultrasonography can also detect the presence of fluid, such as blood or urine. Ultrasound waves cannot penetrate bone, so ultrasonography cannot be used to see objects hidden behind bones, such as the brain.. Because ultrasonography creates images that the doctor sees right away, it can be used to evaluate the heart as it beats for the motion of heart valves and chambers, blood flow through the heart, and contractions of the heart muscle. It can also be used to assess the heart for defects.. Ultrasonography is useful for assessing fetal health and monitoring pregnancy in breeding animals.. Ultrasonography can also play a role in diagnosing and staging cancer. Tumors and masses can be located, counted, and measured using ultrasonography, which can be valuable when a veterinarian is looking for evidence of cancer spread.

Renal biopsy is regarded as the gold standard for the diagnosis, prognosis, and management of patients with renal disease. The first renal biopsy dates back more than a century [4]. Advancements in the needle, as well as use of real-time ultrasonography, have gradually improved the technique and the yields of the biopsies [5]. The safety of the procedure has improved considerably, even in the hands of trainee physicians [5, 6]. However, renal biopsy can cause minor to serious complications. Bleeding manifestations include hematuria, hematoma, and profuse bleeding with a consequent need for blood transfusions, coil embolization, or surgical procedures such as nephrectomy; rarely, death can result [3]. Serious complications are rare when risk factors such as hypertension, bleeding, and clotting tests are within acceptable ranges [7, 8]. Our patient had severe hypertension periprocedurally, which is a well-known risk factor for bleeding. His platelet count and coagulation were within reference ...

Background: Ultrasound has become the most widely practiced medical imaging examination even in developing countries because of its non-irradiating, non-invasive nature and its relatively affordable cost. Objective: The objective of this study was to review the practice of medical ultrasound in Lomé city. We carried out a descriptive cross-sectional study using the pre-established fact sheets. It took place from 16 August to 30 November 2013 in the healthcare facilities of the city of Lomé. Results: A total of 47 centers were surveyed, including 14 public centers and 33 private centers. The ultrasound scanners were mostly acquired in the new state (59.6%) with only 34.1% of these ultrasound scanners equipped with the Doppler mode. There were 3 ultrasound scanners (6.4%) that had a 3D probe. Radiologists were the ones who carried out most of the ultrasound examinations in public centers, while in private they accounted for half of the performers (45.5%). Physicians enrolled in a specialty in radiology

Multiple imaging modalities are currently available to explore bone and soft tissue involvement in RA.7 15 Standard radiology is still the best method for detecting and monitoring erosive changes.16-18 Early depiction of erosions by ultrasonography may have a useful role in assessing the course of the anatomical damage in patients with RA.19 This pictorial essay aimed at demonstrating that ultrasonography with very high frequency transducers can depict bone erosions, especially in the early target areas of bone resorption (second MCP and fifth MTP joints).20-24 These joints can be carefully explored because of the multiplanar capability of ultrasonography.. Our preliminary investigation of a representative group of patients with RA shows that last generation ultrasonography equipment allows a safe, quick, inexpensive, and accurate identification of small bone erosions.. Despite the lack of standardised criteria for sonographic assessment of bone erosions in RA, our pictorial essay provides a ...
Ultrasonic emulsification is caused by coupling the waves of power ultrasound into a liquid system. By sonicating a liquid, two mechanisms occur: (1) The acoustic field generates waves that travel through the liquid and cause microturbulences and an interfacial movement. Thereby, the boundary phase becomes unstable, so that the dispersed (internal) phase eventually breaks and forms droplets in the continuous (external) phase. (2) The application of low-frequency, high power ultrasonics generates cavitation (Kentish et al. 2008). By ultrasonic cavitation, microbubbles or voids are formed in the medium due to the pressure cycles of the ultrasound wave. The microbubbles / voids grow over several wave cycles until they collapse violently. This bubble implosion causes locally extreme conditions such as very high shear, liquid jets, and extreme heating and cooling rates (Suslick 1999). These extreme forces break primary droplets of dispersed (internal) phase down to nanosize droplet and mix them ...

To the Editors:. We appreciate the interest of Guaraldi et al in our recent article on nonalcoholic fatty liver disease (NAFLD) among HIV-infected persons.1 Both our study and a recent article by their group demonstrate the high prevalence (31%-37%) of NAFLD among HIV-positive persons.1,2 Because NALFD is often a silent disease and patients frequently have normal liver tests,1,3 the diagnosis of NAFLD usually relies on radiographic imaging using ultrasound, computed tomography (CT), or magnetic resonance imaging.4 As pointed out by Guaraldi et al, CT and ultrasound may be similar in their detection of NAFLD. Prior reports have shown that ultrasound has a similar sensitivity (80%-100%)5-7 to that cited for CT, and a recent study suggested that ultrasound may be even more sensitive than CT in detecting steatosis in the setting of concurrent fibrosis among patients with nonalcoholic steatohepatitis (NASH).7 These data, along with our study findings, suggest that ultrasound may be useful as an ...

Although 3-D fetal ultrasound can produce more realistic and recognizable images than conventional 2-D ultrasound, the clinical significance of this remains unclear. The perceived superiority of 3-D ultrasound for a number of fetal abnormalities has not been definitively established, and 2-D imaging remains the principal diagnostic modality (Meyer-Wittkopf, 2003; Schellpefeffer, 2013; Voss, 2015). Michailidis and colleagues (2002) noted that real-time 2-D ultrasound is the best way to examine fetal anatomy in the first trimester. A comparison of the diagnostic capabilities of 2-D and 3-D sonography for the study of conjoined twins revealed that 2-D sonography provided more definitive and specific information about shared organs and 2-D sonography is the primary modality for diagnosing and evaluating conjoined twins. Pretorius (2001) reports that although 3-D ultrasound may be useful in evaluating abdominal abnormalities such as bowel obstruction, gastroschisis, omphalocele, and wall defects ...

These hospitals are affiliated with Partners in Health, a US-based nongovernmental organization that provides financial, educational and staff support for providing health care to a population of over 800,000 people in Rwanda.. Prior to beginning the ultrasound training program, a needs assessment was performed by reviewing hospital and clinic logbooks from 2007 to determine which ultrasound applications would likely address the diagnostic concerns of clinicians working with this patient population. Specifically, patient demographics, admission diagnosis, discharge diagnosis, prenatal clinic log information and maternity ward logbooks were reviewed. Results of this review suggested the major causes of patient visits were related to obstetric concerns, tuberculosis (TB), HIV, and malnutrition.. The ultrasound training curriculum spanned nine weeks and included lectures ...

1) Carotid ultrasound: A carotid Doppler ultrasound is a non-invasive test that measures blood flow and plaque through the carotid arteries, which supply blood to the brain. A carotid Doppler ultrasound may be ordered if you have suffered from a stroke before or are at increased risk of having a stroke. Results from a carotid ultrasound can help determine what kind of treatment you may need to lower your risk.. 2) Abdominal aortic aneurysm (AAA) screening: An abdominal aortic aneurysm is a weakened, bulging spot in your abdominal aorta, the artery that runs through the middle of your abdomen and supplies blood to the lower half of your body. An aneurysm that grows and becomes large enough can rupture, causing dangerous bleeding inside the body. An abdominal ultrasound may be used to screen for an abdominal aortic aneurysm. Many cases of ruptured aneurysm can be prevented with early diagnosis and medical treatment. Because aneurysms can develop and become large before causing any symptoms, it is ...
A surgical instrument navigation system comprises an ultrasound machine and a computer coupled to the ultrasound machine. A memory is coupled to the computer and includes computer instructions that when executed by the computer cause the computer to generate an icon representing the surgical instrument with a tip and the surgical instruments trajectory and to overlay the icon on a real-time ultrasound image having an image plane, such that when the surgical instrument crosses the ultrasound image plane the format of the surgical instruments trajectory is changed to represent the surgical instruments crossing of the ultrasound images plane. The system also comprises a localizer coupled to the ultrasound machine, and a display coupled to the computer for displaying the generated icon superimposed on the real-time image.
The use of any micro-mechanical component in an ultrasound system is disclosed. In particular, the use of micro-mechanical ultrasound transducers, micro-relays, micro-switches and inductors in the transducer probe head, in the transducer connector, coupled with the system transducer connector(s) or anywhere else in the system. In an ultrasound system, micro-mechanical components such as micro-mechanical ultrasound transducers, micro-fabricated switches, relays and inductors permit impressive size reduction, cost reduction, signal-integrity enhancement and improved operational flexibility.

Royal Philips, Amsterdam, is debuting the Philips Abdominal Aortic Aneurysm (AAA) Model, which is based on 3D ultrasound. An AAA is an aneurysm that forms in the lower part of the aorta. Typically, AAAs are identified incidentally during abdominal imaging exams but, in some cases, remain undetected until rupture. A ruptured AAA has an 80% mortality rate, emphasizing the importance of routine surveillance. Philips AAA Model integrates advanced software and 3D ultrasound technologies into a single solution to help increase diagnostic confidence. The software automatically segments and quantifies the size of the aneurysm sac for surveillance of known native (untreated), and post-EVAR (treated) AAAs.. The current standard of care for AAAs includes 2D ultrasound and CT angiography (CTA). Each of these modalities has its drawbacks, including inter-operator variability with 2D ultrasound and patient exposure to high levels of radiation and nephrotoxic contrast agents with CTA.. A recent clinical study ...

Software treatment of the ultrasound scan images: Ductus venous monitoring: In this project we present a method of identifying the ductus through a preliminary ultrasonic examination, for further assists the physician in guiding the exploration. To improve ultrasonic measuring equipment are used ultrasonic measurement systems that use the Doppler effect. Thus the speed of the elements observed (usually blood flow) is measured. Calculating the change in frequency of an observed volume, for example the flow in an artery or vein, one can determine and monitor the speed of said flow. Software treatment of the ultrasound scan images: Segmentation of ultrasound images is the determination of the boundaries of structures observed. This way you can detect automatically, dimensions and characteristics of the scanned tissue («tissue Ultrasound characterization»). One of the most important applications of this technique is the detection of tumors in the uterus (both benign (uterine fibroid) and ...

Chest ultrasound is a noninvasive diagnostic exam that produces images, which used to assess the organs and structures within the chest, such as the lungs, mediastinum (area in the chest containing the heart, aorta, trachea, esophagus, thymus, and lymph nodes), and pleural space (space between the lungs and the interior wall of the chest). Ultrasound technology allows quick visualization of the chest organs and structures from outside the body. Ultrasound may also be used to assess blood flow to chest organs ...
Ultrasound technicians (or diagnostic medical sonographers) are people who use ultrasound technology to track the development of the internal organs inside the human body. Ultrasound technicians have a rapidly growing field in front of them with even higher job prospects in the future. Generally, those who aspire to become an ultrasound technician take up a two year degree called associates degree. However, if one already has a medical degree one may even take shorter courses. These courses are taught at community colleges, universities and medical colleges. You will find plenty of such colleges around you. But not all of them provide good quality education.. Once you start your college search, you will come across a lot of options. The first one is what duration of course you choose. As said before, it depends on your needs as well as interests. The second choice you have to make is specialization. Ultrasound has different branches within it: abdominal ultrasound, neuro ultrasound, obstetric ...
