OBJECTIVE Our objective was to determine if there is a single parameter that can be used as a marker of splenomegaly using CT. MATERIALS AND METHODS Splenic length, width, and thickness were measured in 249 CT scans and multidimensional indexes were obtained from the multiplication of these measurements. Volume was calculated by summing the volumes of(More)
PURPOSE To assess the influence of embolic size on the therapy response of prostatic arterial embolization (PAE) based on perfusional changes seen on dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI). MATERIALS AND METHODS Twelve beagles underwent PAE, four dogs with each particle size: A: 100-300 μm; B: 300-500 μm; and C: 500-700 μm. Prior(More)
PURPOSE To assess feasibility and success of venous recanalization in patients with short gut syndrome who have lost their traditional central venous access and required intestinal or multivisceral transplantation. MATERIALS AND METHODS Twelve patients between the ages of 7 and 55 years with short gut syndrome and long-standing total parenteral nutrition(More)
PURPOSE To evaluate the use of radiofrequency (RF) ablation as a primary treatment for symptomatic primary functional adrenal neoplasms and determine the efficacy of treatment with use of clinical and biochemical follow-up. MATERIALS AND METHODS After obtaining institutional review board approval, the authors retrospectively evaluated images and medical(More)
Medical procedures in outpatient settings have limited options of managing pain and anxiety pharmacologically. We therefore assessed whether this can be achieved by adjunct self-hypnotic relaxation in a common and particularly anxiety provoking procedure. Two hundred and thirty-six women referred for large core needle breast biopsy to an urban tertiary(More)
PURPOSE Because many retrievable inferior vena cava (IVC) filters are placed without ever being removed, placement of a retrievable device that is not removed incurs greater technical cost for the institution than a cheaper permanent filter (PF), with no clinical benefit for the patient and no additional professional or technical revenue for the(More)
PURPOSE To retrospectively evaluate solid renal tumor sizes before and after treatment with radiofrequency (RF) thermal ablation to assess for immediate changes on cross-sectional imaging. MATERIALS AND METHODS Medical records were retrospectively reviewed in consecutive patients who underwent percutaneous image-guided RF thermal ablation for solid renal(More)
PURPOSE To determine the success rate for reinsertion of interventional radiology-placed catheters that were accidentally removed by using the existing percutaneous track and to investigate factors that influence success rate. MATERIALS AND METHODS The authors performed a retrospective analysis of 225 patients who presented with dislodged catheters (24(More)
PURPOSE To determine how hypnosis and empathic attention during percutaneous tumor treatments affect pain, anxiety, drug use, and adverse events. MATERIALS AND METHODS For their tumor embolization or radiofrequency ablation, 201 patients were randomized to receive standard care, empathic attention with defined behaviors displayed by an additional(More)
