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)
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)
RATIONALE AND OBJECTIVES To understand the reasons leading to potentially inappropriate management of imaging findings concerning for malignancy and identify optimal methods for communicating these findings to providers. MATERIALS AND METHODS We identified all abdominal imaging examinations with findings of possible cancer performed on six randomly(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)
BACKGROUND Although the Centers for Medicare and Medicaid Services (CMS) denied coverage for screening computed tomography colonography (CTC) in March 2009, little is understood about whether CTC was targeted to the appropriate patient population prior to this decision. OBJECTIVE Evaluate patient characteristics and known relative clinical indications for(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)
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)
Purpose To explore provider and patient characteristics that influence how primary care providers (PCPs) communicate and manage incidental imaging findings. Materials and Methods This HIPAA-compliant study was approved by the institutional review board. Through semistructured interviews, researchers explored concerns and perspectives of 30 PCPs on receiving(More)
