BACKGROUND At teaching hospitals, radiology residents give preliminary reports for imaging studies requested from the Emergency Department (ED). Discrepancy rates between preliminary and final reports represent an important performance indicator. PURPOSE To present a system for feedback and follow-up of discrepancies, identify the variables associated(More)
The purpose of this study is to investigate the effect of the inhaled gas used alongside isoflurane in the anesthetization of small animals on the time-intensity curves (TICs) acquired from ultrasound contrast agents—microbubbles. TICs were recorded over the common iliac vein of 12 mice receiving Definity®. Animals were anesthetized with isoflurane, the(More)
Tracking neuroprogenitor cells (NPCs) that are used to target tumors, infarction or inflammation, is paramount for cell-based therapy. We employed ultrasound imaging that can detect a single microbubble because it can distinguish its unique signal from those of surrounding tissues. NPCs efficiently internalized positively charged microbubbles allowing a(More)
Myelolipoma is an uncommon benign tumor that classically arises in the adrenal glands. Most cases are asymptomatic, with incidental detection of this tumor on cross-sectional imaging performed for other causes. Extra-adrenal occurrence of myelolipoma has been infrequently reported, with scarce radiology literature on the topic. We present radiologic and(More)
A 52-year-old woman presenting with dyspnea was referred for a ventilation and perfusion scan (VQ). VQ images (with Tc-DTPA [diethylene triamine pentaacetic acid aerosol] and Tc-MAA [macroaggregated albumin]) initially appeared normal; however, count rates on perfusion images were similar to ventilation images, implying little Tc-MAA had reached the lungs.(More)
BACKGROUND Vestibular rehabilitation therapy is a well-established treatment modality for patients with vestibular problems. HYPOTHESIS Performing vestibular rehabilitation therapy in a closely monitored setting may result in a better outcome than a home exercise programme. METHODS A retrospective study was conducted of patients undergoing vestibular(More)
BACKGROUND Submucosal resection is accompanied by significant post-operative pain and discomfort. The aim of this randomized, double-blinded clinical trial was to study the efficacy of a local block anaesthetic, delivered after induction of general anaesthesia, in reducing post-operative pain. METHODS Patients aged 16 years and over who were scheduled for(More)
Despite the overwhelming prevalence of cholelithiasis, many health care professionals are not familiar with the basic pathophysiology of gallstone formation. This article provides an overview of the biochemical pathways related to bile, with a focus on the physical chemistry of bile. We describe the important factors in bile synthesis and secretion that(More)
