PURPOSE To assess the effect of a rapid needle-out patient-rollover time approach on the rate of pneumothorax after computed tomography (CT)-guided transthoracic needle biopsy of pulmonary nodules. MATERIALS AND METHODS The institutional review board approved the study, and all patients gave written informed consent. Between January 2008 and December(More)
The term acute aortic syndrome comprises aortic dissection, intramural hematoma, and penetrating atherosclerotic ulcer. The most recent developments in acute aortic syndromes include (1) a change in the mindset that each entity is pathologically distinct, with a shift toward considering the acute aortic syndromes as points along a spectrum of aortic(More)

OBJECTIVE The purpose of this study was to compare the image quality of a standard pulmonary CT angiography (CTA) protocol with a pulmonary CTA protocol optimized for use in pregnant patients with suspected pulmonary embolism (PE). MATERIALS AND METHODS Forty-five consecutive pregnant patients with suspected PE were retrospectively included in the study:(More)
Tracheobronchomalacia (TBM) results from weakness of the airway walls and/or supporting cartilage and affects both adult and pediatric populations. Diagnosing TBM is challenging because symptoms are nonspecific and overlap with those of other chronic respiratory disorders. Recent advances in multidetector computed tomography have facilitated the noninvasive(More)
PURPOSE To determine the best radiographic landmark for the cavoatrial junction (CAJ) using electrocardiographic-gated, 64-row multidetector coronary computed tomographic angiography (CTA). MATERIALS AND METHODS Institutional Review Board approval was obtained. Patient age, sex, weight, and height were recorded. The CAJ was localized by 2 readers using(More)
