Objectives We sought to demonstrate the long-term natural course of descending aorta
dilation after acute aortic dissection (AD) and identify early predictors for late aneurysmal
change. Background Aneurysmal dilation of the aorta is a critical late complication in AD …

The objective of this study was to compare the capability of arterial, portal venous, and
delayed phases of helical CT with that of iodized-oil CT for revealing nodular hepatocellular
carcinomas. Forty-eight patients with nodular hepatocellular carcinomas underwent triphasic …

Study objectives To investigate the histopathologic pattern and clinical features of patients
with rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) according to the
American Thoracic Society (ATS)/European Respiratory Society consensus classification of …

PURPOSE: To describe findings of pulmonary tuberculoma at 2-[fluorine 18] fluoro-2-deoxy-
d-glucose (FDG) positron emission tomography (PET). MATERIALS AND METHODS: Ten
consecutive patients who underwent PET and subsequently were proved to have pulmonary …

Congenital abnormalities of the coronary arteries are an uncommon but important cause of
chest pain and, in some cases of hemodynamically significant abnormalities, sudden
cardiac death. For several decades, premorbid diagnosis of coronary artery anomalies has …

Typical radiologic findings of a pulmonary metastasis include multiple round variable-sized
nodules and diffuse thickening of interstitium. In daily practice, however, atypical radiologic
features of metastases are often encountered that make distinction of metastases from other …

PURPOSE: To determine the radiographic and computed tomographic (CT) findings and
clinical features of mucoepidermoid carcinoma of the tracheobronchial tree. MATERIALS
AND METHODS: Chest radiographic and CT findings and clinical features of 12 …

Purpose: To determine the clinical utility of dual-energy computed tomography (CT) in
evaluating solitary pulmonary nodules (SPNs). Materials and Methods: This study was
approved by the institutional review board, and informed consent was obtained. CT scans …

Institutional review board approval and written informed consent were obtained. Although
xenon (Xe) ventilation CT has been introduced as a potential method with which to depict
regional ventilation, quantification of Xe enhancement has been limited by the variability of …
