Solitary pulmonary nodule (SPN) is a diagnostic challenge for both radiologists and physicians. There have been numerous common and uncommon causes of SPN. We report a30-year-old Indian man with pulmonary thromboembolism, where the pulmonary thrombus was seen as a SPN on the chest radiograph. To the best of our knowledge, this observation has not been published in the literature.. Keywords: chronic pulmonary thromboembolism, lung mass, pulmonary nodule, pulmonary thrombus, solitary pulmonary ...

Fluorodeoxyglucose (FDG)-positron emission tomography (PET) has proved to be an accurate non-invasive imaging test for differentiating benign from malignant solitary pulmonary nodules (SPNs).1-4 However, some types of cancers, e.g. carcinoid tumours and bronchoalveolar carcinoma, have low FDG uptake that can give false-negative results. Many benign processes such as infection, inflammation and granulomatous diseases, especially tuberculosis (TB), present as SPNs with enhanced FDG uptake leading to false-positive findings.5,6 Since TB is more prevalent in South Africa than in developed countries, it may be anticipated that the accuracy of FDG-PET in differentiating benign from malignant SPNs will be significantly worse owing to a drop in specificity.. Over time the uptake of FDG continues to increase in malignant lesions, whereas it decreases or remains stable in benign lesions.7-9 It was therefore deduced that dual time-point imaging might further improve the accuracy of FDG-PET to distinguish ...

Objective. Fluorodeoxyglucose (FDG)-positron emission tomography (PET) is an accurate non-invasive imaging test for differentiating benign from malignant solitary pulmonary nodules (SPNs). We aimed to assess its diagnostic accuracy for differentiating benign from malignant SPNs in a tuberculosis (TB)-endemic area. Methods. Thirty patients, 22 men and 8 women, mean age 60 years, underwent dual time point FDG-PET/computed tomography (CT) imaging, followed by histological examination of the SPN. Maximum standard uptake values (SUVmax) with the greatest uptake in the lesion were calculated for two time points (SUV1 and SUV2), and the percentage change over time per lesion was calculated (%DSUV). Routine histological findings served as the gold standard. Results. Histological examination showed that 14 lesions were malignant and 16 benign, 12 of which were TB. SUVmax for benign and malignant lesions were 11.02 (standard deviation (SD) 6.6) v. 10.86 (SD 8.9); however, when tuberculomas were excluded from

An automated method for analyzing a nodule and a computer storage medium storing computer instructions by which the method can be implemented when the instructions are loaded into a computer to program the computer. The method includes obtaining a digital image including the nodule; segmenting the nodule to obtain an outline of the nodule, including generating a difference image from chest image, identifying image intensity contour lines representative of respective image intensities in a region of interest including the nodule, and obtaining an outline of the nodule based on the image intensity contours; extracting features of the nodule based on the outline; applying features including the extracted features to at least one image classifier; and determining a likelihood of malignancy of the nodule based on the output of the at least one classifier. In one embodiment, extracted features are applied to a linear discriminant analyzer and/or an artificial neural network analyzer, the outputs of

Background: The discovery of a solitary pulmonary nodule (SPN) on a chest imaging exam is of major clinical concern. However, the incidence rates of SPNs in a general population have not been estimated. The objective of this study was to provide incidence estimates of SPNs in a general population in 5 northeastern regions of France. Methods: This population-based study was undertaken in 5 regions of northeastern France in May 2002-March 2003 and May 2004-June 2005. SPNs were identified by chest CT reports collected from all radiology centres in the study area by trained readers using a standardised procedure. All reports for patients at least 18 years old, without a previous history of cancer and showing an SPN between 1 and 3 cm, were included. Results: A total of 11,705 and 20,075 chest CT reports were collected for the 2002-2003 and 2004-2005 periods, respectively. Among them, 154 and 297 reports showing a SPN were included, respectively for each period. The age-standardised incidence rate (IR)

A solitary pulmonary nodule (SPN) or coin lesion is a mass in the lung smaller than 3 centimeters in diameter. It can be an incidental finding found in up to 0.2% of chest X-rays and around 1% of CT scans. The nodule most commonly represents a benign tumor such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer, especially in older adults and smokers. Conversely, 10 to 20% of patients with lung cancer are diagnosed in this way. If the patient has a history of smoking or the nodule is growing the possibility of cancer may need to be excluded through further radiological studies and interventions, possibly including surgical resection. The prognosis depends on the underlying condition. Nodular density is used to distinguished larger lung tumors, smaller infiltrates or masses with other accompanying characteristics. An often used formal radiological definition is the following: a single lesion in the lung completely surrounded by lung parenchyma (functional ...

A bronchoscope can be inserted through the mouth area or nasal area and down the windpipe. From there, it could be inserted in to the airways of the lung area. During bronchoscopy, the ongoing healthcare professional requires a biopsy sample from the solitary pulmonary nodule. If the lesion isnt easy to get at on the airway wall structure or is smaller sized than 2 cm in size, a needle biopsy could be performed. This method is named a transbronchial needle aspiration biopsy. Generally, this system is only successful using endobronchial ultrasound . Transthoracic needle aspiration biopsy: This kind of biopsy can be used if the lesion isnt easy to get at on the airway wall structure or is smaller sized than 2 cm in size. If the solitary pulmonary nodule can be on the periphery of the lung, a biopsy sample needs to be taken by using a needle inserted through the upper body wall and in to the solitary pulmonary nodule.

AU - Ishibashi, Tadashi. AU - Yoshizawa, Makoto. PY - 2009. Y1 - 2009. N2 - In this paper, we develop a lung area extraction technique from X-ray computed tomography (CT) images for computer-aided diagnosis (CAD) systems. In lung cancer cases, pulmonary nodules are typical pathological changes and thus they are the target to be detected by CAD systems. The isolated nodules can be detected more easily by CAD systems developed previously, while previous CAD systems are often hard to detect non-isolated nodules. The extraction technique can then be used for transforming the non-isolated pulmonary nodules connected to the walls of the chest into isolated ones. The technique proposed here is based on an active contour model, but such model is often trapped into a local optimum solution. To avoid the local optimum ...

Pulmonary nodules or lung nodules are small round or oval shaped growth in the lung. It is also called spot on lung or coin lesion. Most nodules are small 1 to 1.2 inches in diameter. Larger nodules are called lung mass.. Nodule could be malignant (cancer) versus benign (noncancerous). Over 90% small pulmonary nodule are benign. Benign nodule could be ascar from prior infection, granulomas, infection and other conditions. Malignant nodules include primary lung cancer, lymphoma, carcinoid, sarcoma and metastatic nodules- tumors that have spread to lung from cancer in another body part.. Most nodules are asymptomatic and usually found on CXR or CT chest done for some other reasons. Larger lung mass can cause chest pain, cough, hemoptysis. Benign small nodules are commonly seen on CT chest. Usual test done during workup includes chest X-ray, CTchest, and PET scan. If thenodule is large or growing on serial CT chest, abiopsy is recommended or complete removal by thoracoscopic surgery. A biopsy can ...

Percutaneous transthoracic needle biopsies (PTNB) are widely used for the diagnosis of a peripheral pulmonary nodules, but the risk of pleural recurrence in lung cancer patients remains undetermined. Our meta-analysis aims to answer the question whether PTNB strategy increases the risk of recurrence. PubMed, EMBASE, The Cochrane Library, and China National Knowledge Infrastructure (CNKI) were searched from inception to January 9, 2016. A total of 1242 patients from 5 studies were included. The results showed that PTNB does not increase risk of total recurrence (Odds Ratio,0.78; 95% CI, 0.53 to 1.15) or pleural recurrence (Odds Ratio,1.58; 95% CI, 0.41 to 6.12) compared with non-PTNB strategies in early stage lung cancer patients. Subgroup analysis showed that PTNB was associated with increased pleural recurrence (Odds Ratio, 10.76; 95% CI, 2.92 to 39.70) in patients with sub-pleural lesions but not in patients without sub-pleural lesions (Odds Ratio, 0.96; 95% CI, 0.24 to 3.89). In conclusion, PTNB

Pulmonary nodules (PN), frequently found on imaging studies, represent a diagnostic challenge during the follow up of cancer patients. However, published data regarding investigation of PNs incidentally found on chest imaging is scarce. The PN may be present at the time of cancer diagnosis, or arise during the treatment or follow-up periods. In the context of the oncologic patient these lesions are quite invariably considered as metastases, what impacts directly on patients treatment and prognosis. The present study reports 2 cases of pulmonary nodules found in two patients already diagnosed with cancer. Case 1 referred to a woman with squamous cell carcinoma and two pulmonary nodules, and in case 2 the patient was diagnosed with duodenal adenocarcinoma. Both patients were submitted to pulmonary biopsies before the oncologic treatment. In both cases the nodules were of infectious origin, what changed significantly the neoplasia staging and the oncologic treatment intention. The authors performed ...

Background: The recent National Lung Cancer Screening Trial (NLST) has proven that screening for lung cancer by low dose CT (LDCT) scans reduces the related mortality rate by 20%. However, in this program, the false positive rate was extremely high: 96% out of the 24% positive CT findings were non-cancerous. A high rate of false positives leads to unnecessary invasive procedures, which are both costly and associated with significant morbidity and mortality. It is now widely anticipated that LDCT screening programs will be launched in many countries in the near future. This will lead to a dramatically increased detection of small solitary pulmonary nodules (SPNs) for invasive investigation. Consequently, additional non-invasive biomarker approach to distinguish between benign and cancerous conditions is necessary. For that purpose, we evaluated in this study the role of exhale breath analysis as a potential non-invasive biomarker to discriminate between benign and malignant SPNs in the post ...

Evaluation of Pulmonary Nodules Using the Spyglass Direct Visualization System Combined With Radial Endobronchial Ultrasound: A Clinical Feasibility Study

Picture the scene: a lung cancer multidisciplinary team (MDT) meeting, somewhere in the UK, January 2015. CT images from a patient with suspected colorectal cancer, whom no one present has ever met, are discussed at the request of the colorectal team. An abnormality is present in the right lower lobe of lung. A week earlier, following two clicks and a drag from the colorectal radiologists mouse, a 5 mm incidental pulmonary nodule was identified and is now destined to take its unwitting host on an unpredictable journey, which may span years. Imperfectly remembered advice from multiple professional society guidelines, some a decade old, will be proffered and contested in repeated meetings. How should the nodule be measured, how often, by whom? What is the risk that it is malignant? Is now (ever?) the right time for a biopsy? This scenario, which is likely familiar to many readers, has often served to relegate nodule follow-up to a tedious chore shared widely to ease the burden.. Help is at hand. ...

ICD-9 code 793.11 for Solitary pulmonary nodule is a medical classification as listed by WHO under the range - NONSPECIFIC ABNORMAL FINDINGS (790-796)

OCC File number: 2011-7920 History:. The decedent was an 80-year-old male who was found to have an incidental, solitary pulmonary nodule in his right lung following routine radiographic imaging of his chest in April 2011 to assess a previously implanted endovascular stent within his thoracic aorta. This nodule was reported to be pleural based within the right upper lobe and approximately 1.4 cm in greatest dimension. An ultrasound-guided fine needle aspirate of this nodule in the anterior segment of the right upper lobe was obtained on April 26, 2011 and reported as Positive for Malignant Cells / Non-Small Cell Carcinoma. A whole body Positron Emission Tomography - Computed Tomography (PET-CT) scan was performed which demonstrated that the nodule was 15 mm x 13 mm and metabolically active. No evidence of metabolically active foci was identified within the intrathoracic lymph nodes or elsewhere to suggest metastatic disease. [Of note, in the body of this PET-CT report, the nodule is recorded as ...

BACKGROUND: The new technique chest tomosynthesis refers to the principle of collecting low-dose projections of the chest at different angles and using these projections to reconstruct section images of the chest at a radiation dose comparable to that of chest radiography. PURPOSE: To investigate if, for experienced thoracic radiologists, the detectability of pulmonary nodules obtained after only a short initial learning period of chest tomosynthesis improves with additional clinical experience of the new technique. MATERIAL AND METHODS: Two readings of the same clinical chest tomosynthesis cases, the first performed after 6 months of clinical experience and the second after an additional period of 1 year, were conducted. Three senior thoracic radiologists, with more than 20 years of experience of chest radiography, acted as observers, with the task of detecting pulmonary nodules in a jackknife free-response receiver operating characteristics (JAFROC1) study. The image material consisted of 42 ...

An optical waveguide is constructed so as to comprise a non-solid core layer surrounded by a solid-state material, wherein light can be transmitted with low loss through the non-solid core layer, and an electrical component is in fluid communication with the non-solid core layer. The electrical component controls movement of sample material through the non-solid core. The optical wave guide provides light confinement with structured dielectric materials. A presently preferred implementation of the invention employs anti-resonant reflecting optical waveguides (ARROWs or ARROW). Liquid-core waveguides may also be implemented using other dielectric confinement methods where the layers are periodic, such as Bragg mirrors, holey photonic crystal fiber, and omniguides.
