PURPOSE To prospectively ascertain what characteristics of radiologists, their practices, and their work environment affect professional satisfaction and to describe recent changes in satisfaction. MATERIALS AND METHODS Survey respondents were guaranteed confidentiality. Those who consented to participate were informed of the nature of the study. The(More)
Imaging clinical decision support (CDS) systems provide evidence for or against imaging procedures ordered within a computerized physician order entry system at the time of the image order. Depending on the pertinent clinical history provided by the ordering clinician, CDS systems can optimize imaging by educating providers on appropriate image order entry(More)
This study examined the effects of fetal alcohol exposure (FAE) on serotonin transporter (5-HTT) binding sites in the brains of developing male and female rat offspring using the technique of quantitative autoradiography. Time-pregnant dams were fed liquid ethanol diet, isocaloric diet without ethanol or normal rat chow. Male and female offspring were(More)
WKY rats develop more restraint-induced gastric ulcers and exhibit more depressive behavior compared to other rat strains. Exposure to novel stressors for 21 days exacerbates depressive behavior in WKY rats and alters beta-adrenoceptors (beta-ARs) and norepinephrine transporter (NET) sites in several limbic brain regions when compared to Sprague-Dawley(More)
AIM To determine the frequency of left ventricular myocardial fat in patients with computed tomography (CT) findings of chronic left ventricular myocardial infarction, and to review the typical CT imaging features. MATERIALS AND METHODS A retrospective search of the CT and nuclear scintigraphy reports from 1998-2005 for chronic left ventricular myocardial(More)
RATIONALE AND OBJECTIVES This study summarizes the literature on the detection of cancer among indeterminate extracolonic findings on computed tomographic (CT) colonography in five targeted organs. MATERIALS AND METHODS We searched PubMed for English-language literature published between January 1, 1994, and December 31, 2010. We describe extracolonic(More)
Findings of anterior abdominal wall hernias at computed tomography and magnetic resonance imaging are well documented; however, little information is available about the depiction and characterization of such hernias in barium studies, primarily in small-bowel follow-through examinations. Such examinations are performed frequently, and radiologists should(More)
Our objective was to assess the role of quantitative Doppler vascularity in differentiating malignant and benign thyroid nodules. Color Doppler images of 100 nodules were analyzed for three metrics: vascular fraction area, mean flow velocity index and flow volume index in three regions (nodule center, nodule rim and surrounding parenchyma). Vascular(More)
PURPOSE To assess the findings of recurrent Crohn's disease in the neoterminal ileum on small bowel follow through (SBFT) and computed tomography (CT) as well as the overall diagnostic performance of these imaging tests. METHODS Our radiology database yielded 52 patients with an ileocolic anastomosis for Crohn's disease who underwent SBFT and CT. The(More)
