Mechanical efficiency, patient acceptability and minimal biochemical perturbation are important factors in the choice of lavage solution for bowel preparation. This prospective randomised trial of 59 patients compared a polyethylene glycol bowel lavage solution (Klean Prep) to a sodium picosulphate solution (Picolax) considering their efficacy from both(More)
PURPOSE To compare accelerated real-time two-dimensional (2D) and segmented three-dimensional (3D) cine steady-state free precession magnetic resonance (MR) imaging techniques by using a 32-channel coil with a conventional 2D cine imaging approach for imaging the heart and to evaluate any difference caused by free breathing and breath holding for real-time(More)
OBJECTIVE The purpose of this study was to compare metal artifact reduction techniques at 1.5-T and 3-T MRI. MATERIALS AND METHODS A titanium plate with steel screws was placed in a freshly harvested pig leg. The leg was imaged with 1.5-T and 3-T MRI. A T2-weighted turbo spin-echo sequence was used with echo-train lengths of 8, 16, 32, and 64 and a(More)
PURPOSE To evaluate the circumstances and determine the outcomes of medical emergencies (MEs) and cardiopulmonary arrests (CPAs) in patients undergoing interventional radiology (IR) procedures. MATERIALS AND METHODS Retrospective review of all MEs and CPAs that occurred between July 2006 and December 2011 was performed. Procedure type, technical outcome,(More)
PURPOSE To investigate retrospectively the use of catheter-based intraaccess blood flow measurements as an adjunct to physical examination and fistulography in hemodialysis access interventions. MATERIALS AND METHODS Among 1,540 dialysis interventions performed at a single institution in a 2.5-year period, 104 qualifying catheter-based flow measurements(More)
PURPOSE To determine the outcomes of patients with spontaneous extraperitoneal hemorrhage (SEH) referred for endovascular therapy. MATERIALS AND METHODS A retrospective analysis included 25 patients (13 male) with 28 spontaneous bleeding events that occurred during the period 1998-2009. All patients had a computed tomography (CT) scan showing(More)
PURPOSE To evaluate a chest x-ray-based algorithm for managing malfunctioning ports. MATERIALS AND METHODS A review of interventional radiology procedures on malfunctioning ports during the period 2000-2012 was performed. Events were divided into two periods: before and after implementation of an algorithm beginning with tip position evaluation using a(More)
BACKGROUND This is a study using Evidence Based Practice (EBP) technique to evaluate if non-calcified renal lesions detected with ultrasound, suspected to represent an angiomyolipoma (AML), need a CT to rule out a renal cell carcinoma (RCC). METHODS The secondary and primary literature were searched for all relevant information. This was appraised for(More)
OBJECTIVE Delayed enhancement MRI using fast segmented k-space inversion recovery (IR) gradient-echo imaging is a well established "bright-blood" technique for identifying myocardial infarction and is used as the reference standard sequence in this study. The purpose of this study was to validate a recently developed dark blood-pool delayed enhancement(More)
The purpose of this study was to compare a navigator gated free breathing 3D Phase Sensitive Inversion Recovery (PSIR) TurboFLASH to an established 2D PSIR TurboFLASH method for detecting myocardial late gadolinium hyperenhanced lesions caused by infiltrative and non-ischemic cardiomyopathy. Under an IRB approved protocol; patients with suspected(More)
