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)
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 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)
OBJECTIVE The purpose of this study was to investigate the utility of bolus-triggering data from pulmonary CT angiography for predicting the diagnosis of pulmonary hypertension (PH) and right ventricular dysfunction (RVD) and to test its performance against previously established CT signs of PH. MATERIALS AND METHODS Automated bolus-triggering data from(More)
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). The secondary and primary literature were searched for all relevant information. This was appraised for validity and strength.(More)
The clinical and radiographic findings in 10 children with neuroblastoma presenting with opsomyoclonus are described and the literature is reviewed. Children with opsomyoclonus are often a diagnostic dilemma, as they may not have a palpable tumor or increased urinary catecholamines. Computed tomography (CT) is the most sensitive imaging method in locating(More)
A patient with Menkes' syndrome is reported. This patient has survived to the age of six years without mental retardation, and shows previously unreported computed tomographic (CT) findings of tortuous vessels and unusual osseous manifestations of undertubulation of long bones and posterior vertebral body scalloping.
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)
