PURPOSE To describe results of a planned interim analysis of a prospective, randomized clinical trial developed to compare treatment outcomes among patients with newly diagnosed hepatocellular carcinoma (HCC). METHODS AND MATERIALS Eligible subjects had either clinical or pathologic diagnosis of HCC and met either Milan or San Francisco transplant(More)
PURPOSE Computed tomography (CT) scans are a significant source of radiation to patients. It was hypothesized that technical success and complication rates would not be significantly changed by radically lowering the CT dose during lung biopsies with an ultra-low-dose (ULD) protocol. MATERIALS AND METHODS A total of 100 consecutive patients aged 11-89(More)
PURPOSE Unenhanced multidetector computerized tomography is the imaging modality of choice for urinary calculi but exposes patients to substantial radiation doses with a subsequent risk of radiation induced secondary malignancy. We compared ultra low dose and conventional computerized tomography protocols for detecting distal ureteral calculi in a cadaveric(More)
BACKGROUND AND AIMS Increased levels of nitric oxide (NO) are hypothesized to contribute to renal dysfunction in patients with decompensated cirrhosis. In this study, we examined whether splanchnic and/or peripheral NO levels and L-arginine (L-Arg) correlate with progressive renal dysfunction in cirrhotics. METHODS Serum NO metabolites (NOx) and L-Arg(More)
Twenty-four patients with massive rectal hemorrhage and known or subsequently proved colonic diverticular disease had the bleeding site localized by mesenteric angiography and received intra-arterial infusion of vasopressin to arrest the bleeding. In twenty-two patients the bleeding was controlled with the vasopressin infusion whereas in the remaining two,(More)
Angiographic methods were applied to control bleeding in 2 patients following genitourinary tract operations. In 1 patient hemorrhage into the prostatic bed after needle biopsy of the prostate was controlled with embolic occlusion of branches of the hypogastric arteries. In the second patient bleeding from the ileum following ileal loop cutaneous diversion(More)
BACKGROUND AND PURPOSE Automatic brightness control (ABC), a function of modern fluoroscopy machines, adjusts radiation intensity in real time to enhance image quality. While shielding reduces radiation exposure to protected areas, it is unknown how much radiation adjacent unshielded areas receive when using ABC settings. Our purpose was to assess radiation(More)
PURPOSE To determine if contrast-enhanced multidetector computed tomography (CT) can demonstrate the "corona mortis" (translated as "crown of death"), a common variant obturator artery originating from the external iliac artery system that is susceptible to pelvic trauma. METHODS AND MATERIALS A representative case study is described. The authors(More)
