Chest wall lesions are relatively uncommon and may be challenging once they are encountered on images. Radiologists may detect these lesions incidentally at examinations performed for other indications, or they may be asked specifically to evaluate a suspicious lesion. While many chest wall lesions have characteristic imaging findings that can result in an accurate diagnosis with use of imaging alone, other entities are difficult to distinguish at imaging because there is significant overlap among them.

This article will review the utility of abdominal MRI sequences to diagnose lower chest pathology while providing a systematic pictorial review of imaging findings in the lungs, pleura, mediastinum and chest wall. We will discuss the MRI appearance of lung nodules and masses, lung infiltrates, pulmonary infarction, pulmonary embolism, empyema, pleural effusions and thickening, mediastinal lesions and lymphadenopathy, cardiac thrombus and masses, and breast lesions.

Infection of the prosthetic is a rare, but devastating complication which may result in the well-known aortoenteric or aortobronchial fistulae. Bronchoesophageal fistula resulting from an infected aortic endograft has not yet been reported in the literature.

This technique has not been routinely implemented for 3D printing in CHD. We describe our case series of models printed from RA and validate our technique.

Introduction: Numerical classification systems for the internal carotid artery (ICA) are available, but modifications have added confusion to the numerical systems. Furthermore, previous classifications may not be applicable uniformly to microsurgical and endoscopic procedures. The purpose of this study was to develop a clinically useful classification system.

Intravenous contrast material-enhanced (100 mL of Omnipaque 350; GE Healthcare, Princeton, NJ) computed tomographic (CT) pulmonary angiography was performed to evaluate for pulmonary embolism. On the basis of the CT pulmonary angiographic findings, chromogranin A and 5-hydroxyindoleacetic acid levels were measured and were 7 nmol/L (343 µg/L) (high) and 2.
View Article and Find Full Text PDFSjögren syndrome (SS) is an autoimmune disease with exocrine glands dysfunction and multiorgan involvement. It is associated with increased risk of lymphoproliferative disorders, especially B-cell marginal zone lymphoma. While the role of F-18 Fluorodeoxyglucose position emission tomography/computed tomography (F-18 FDG PET/CT) for evaluation of lymphoma has been established, its use in patients with a chronic history of SS to evaluate for possible lymphoproliferative disorders or multiorgan involvement is limited.

Materials And Methods: About 1200 PET/CT scans were retrospectively reviewed over 20 months for the presence of FDG-avid cardiophrenic lymph nodes. The SUVmax was used to quantify the metabolic activity in each of the lymph nodes.
Unlabelled: (18)F-FDG muscle uptake is evident in some benign physiologic processes as seen in the respiratory muscles of patients with chronic obstructive pulmonary disease (COPD) and labored breathing. The purpose of this study was to correlate the presence of COPD with the patterns of (18)F-FDG uptake by muscles as demonstrated by PET/CT scans.
Methods: (18)F-FDG PET/CT scans and pulmonary function tests (PFTs) were performed for 63 consecutive patients with newly diagnosed or highly suspected lung cancer.
Objective: To determine whether critically ill patients who receive allogenic packed red blood cell transfusions are at increased risk of developing nosocomial infections during hospitalization.
Design: Retrospective database study utilizing Project IMPACT.
Setting: A 40-bed medical-surgical-trauma intensive care unit in an 825-bed tertiary referral teaching hospital.
