Computed tomography (CT) plays a pivotal role in the detection, characterization, and staging of lung cancer and other thoracic malignancies. Since the introduction of clinically viable dual-energy CT techniques, substantial evidence has accumulated on the use of this modality for imaging chest malignancies. This article describes the principles of dual-energy CT along with suitable image acqui...

OBJECTIVE We observed patients in whom the fluid collection in the right lateral portion of the superior aortic recess on computed tomography (CT) scans mimicked a right anterior mediastinal mass on chest PA radiographs. The purpose of this study was to assess chest PA and CT features of these patients. MATERIALS AND METHODS All chest PA radiographs and CT scans in 9 patients were reviewed by...

We herein report a case of invasive candidiasis presenting rare findings on chest computed tomography (CT). The chest CT scan showed multiple small cavitary lesions and nodules with surrounding ground-glass opacity, and also bilateral pleural effusion. Although this CT finding is thought as specific for pulmonary aspergillosis, two sets of blood culture specimens were drawn which yielded Candid...

introduction: using pan or selective computed tomography (ct) scan in management of multiple trauma patient is a matter of debate. therefore, the present study was designed aiming to compare the findings of pan and selective ct scans in management of multiple trauma patients. method: this is a prospective cross-sectional study, on patients presented to the emergency department (ed) of shohadaye...

Chest radiography, CT, and MR imaging were performed in a 3-year-old girl who had posterior mediastinal fibromatosis with transforaminal intraspinal and chest wall extension. Chest radiographs and CT scans showed a slow-growing, noncalcified but locally aggressive left paravertebral mass. The mass was slightly hyperintense relative to muscle on both T1-weighted and fast spin-echo T2-weighted MR...

Forty-five computerized tomographic (CT) chest studies were performed on workers suspected of having pleural disease after being exposed to asbestos material. Ten of the 45 reviewed were court cases, and 32 workers acutely exposed at University of California-Los Angeles (UCLA) were studied with routine four views of the chest. CT confirmed the initial interpretation of chest films obtained at U...

HYPOTHESIS Headmix and head registers use cricothyroid (CT) muscle dominant voicing, whereas chest and chestmix registers use thyroarytenoid (TA) muscle dominant voicing. STUDY DESIGN Cross-sectional study. METHODS CT and TA electromyographic data obtained from five untrained singers and two trained singers were analyzed to determine CT and TA muscle dominance as a function of register. Sim...

Abstracts: Dural ectasia is circumferential expansion or dilatation of the dural sac, and has been frequently reported in association with type 1 neurofibromatosis (NF1). It should be differentiated from posterior mediastinal tumors such as neurofibroma, neuroblastoma, and ganglioneuroma because NF-1 has a high risk of tumor formation. In the spinal deformities of NF-1 patients, despite the sco...

STUDY OBJECTIVES To determine the etiology and the clinical and radiographic predictors of the etiology of pulmonary nodules in a group of HIV-infected patients. DESIGN Retrospective analysis. SETTING A large urban hospital in San Francisco, CA. PATIENTS HIV-infected patients evaluated at San Francisco General Hospital from June 1, 1993, through December 31, 1997, having one or more pulmo...
