OBJECTIVE The purpose of this study was to evaluate morphologic features predictive of benign thyroid nodules. MATERIALS AND METHODS From a registry of the records of 1,232 fine-needle aspiration biopsies performed jointly by the cytology and radiology departments at a single institution between 2005 and 2007, the cases of 650 patients were identified for(More)
PURPOSE To assess diagnostic sensitivity of radial T1-weighted gradient-echo (radial volumetric interpolated breath-hold examination [VIBE]) magnetic resonance (MR) imaging, positron emission tomography (PET), and combined simultaneous PET and MR imaging with an integrated PET/MR system in the detection of lung nodules, with combined PET and computed(More)
PURPOSE To retrospectively evaluate the frequency of recommendations for additional imaging (RAIs) for important extracolonic findings and polyp prevalence among a cohort of seniors (age ≥ 65 years) and nonseniors (age < 65 years) undergoing low-dose computed tomographic (CT) colonography. MATERIALS AND METHODS Institutional review board approval was(More)
The aim of this study was to assess for an association between radiologists' turnaround time (TAT) and report quality for emergency department (ED) abdominopelvic CT examinations. Reports of 60 consecutive ED abdominopelvic CT studies from five abdominal radiologists (300 total reports) were included. An ED radiologist, abdominal radiologist, and ED(More)
Despite limitations, high-resolution computed tomography (HRCT) continues to be the gold standard for establishing the anatomic extent and severity of bronchiectasis. HRCT allows insight into the physiologic consequences of bronchiectasis. Recent reports show that there is good correlation between measurements of the density of airway walls and airway(More)
In contrast to routine flexor tendon injuries, flexor tendon ruptures following blunt injury or re-ruptures following repair can be difficult to diagnose. The authors investigated the efficacy of using ultrasound to assist in the diagnosis. From 1996 to 1997, 8 patients underwent evaluation of the flexor tendons using an ATL HDI-3000 ultrasound machine with(More)
The radiographic manifestations of renal osteodystrophy may be articular as well as osseous. The latter are well recognized, i.e., subperiosteal and subchondral bony resorption. Recently attention has been directed to the occurrence of an erosive arthritis of the hands and wrists in hyperparathyroidism. The authors present six patients with humeral head(More)
The case of a 64-year-old white man with acquired immunodeficiency syndrome and ruptured abdominal aortic aneurysm infected with Salmonella is presented. Five points related to this case are addressed. It is feared that the vascular surgeon may face patients with acquired immunodeficiency syndrome and abdominal aortic aneurysms infected with Salmonella with(More)
