The objective of this paper was to determine the criteria for differentiation of ampullary tumor from benign papillary stricture using thin-section multidetector CT images. Multidetector CT images with 2.5 mm slice-thickness in 57 consecutive patients (24 with ampulla of Vater tumor and 33 with benign papillary stricture) with extrahepatic duct dilatation(More)
Contrast material-enhanced Doppler or gray-scale harmonic ultrasonography (US) may help determine the completeness or long-term therapeutic efficacy of radio-frequency (RF) ablation of hepatocellular carcinoma (HCC). Successfully treated HCC is devoid of vascularity at color or power Doppler US. When the tumor is not completely treated, residual viable(More)
OBJECTIVE To identify the optimal pulse sequence for ferumoxides-enhanced magnetic resonance (MR) imaging in the detection of hepatocelluar carcinomas (HCCs). MATERIALS AND METHODS Sixteen patients with 25 HCCs underwent MR imaging following intravenous infusion of ferumoxides. All MR studies were performed on a 1.5-T MR system, using a phased-array coil.(More)
The purpose of this study was to assess the usefulness of percutaneous intervention with transarterial approach in the salvage of nonmaturing native fistulas status post transvenous approach failure. Eight patients (M:F = 2:6; mean age, 56.8 years) underwent percutaneous intervention with antegrade transarterial approach when the retrograde transvenous(More)
To evaluate the feasibility and efficacy of transrenal ureteral occlusion with microcoils in patients with ureterovaginal fistulas Five women (median age 44 years, range 26–51 years) with ureterovaginal fistulas were treated by transrenal ureteral occlusion with microcoils. The underlying diseases were uterine fibroids (n = 3), a primitive neuroectodermal(More)
BACKGROUND We sought to evaluate the diagnostic use of multidetector computed tomography (MDCT) cholangiography with multiplanar reformation (MPR) for the assessment of patients with biliary obstruction. METHODS MDCT cholangiography with the MPR technique was performed in 58 patients who were thought to have biliary obstruction. No cholangiographic(More)
The purpose of this study was to assess the efficacy of a new perfused-cooled electrode that uses a single pump for creating a large ablation zone in explanted bovine liver. This was done by comparing with the radiofrequency (RF) ablation zones that were created with a monopolar cooled electrode to the RF ablation zones that were created by the new(More)
PURPOSE The purpose of our study was to assess the value of additional early arterial phase computed tomography (CT) imaging in the detection of hepatocellular carcinoma (HCC) by comparing three-phase and four-phase imaging by using multidetector row helical CT. METHODS Twenty-five patients with 33 HCCs underwent four-phase helical CT imaging. The(More)
