The purpose of this study was to evaluate anisotropy of the kidney by measurements of the apparent diffusion coefficient (ADC) using commercially available magnetic resonance (MR) imaging. Fifty-one consecutive patients underwent diffusion-weighted echoplanar MR imaging of the upper abdomen with five different strengths of motion probing gradients (b =(More)
PURPOSE To characterize the appearance of hemagiomas at two-phase dynamic incremental computed tomography (CT) and to determine the cause of contrast material enhancement of adjacent parenchyma in the first series. MATERIALS AND METHODS Contrast-enhanced CT images of 51 hemangiomas in 20 patients were reviewed. Enhancement patterns of hemangiomas in the(More)
PURPOSE To evaluate the segmental anatomy of the liver under the right side of the diaphragm with axial computed tomography (CT). MATERIALS AND METHODS Forty-six patients underwent CT arteriography with selective catheterization of the right hepatic artery in 25 cases, the left hepatic artery in 12, the anterior branch of the right hepatic artery in six,(More)
PURPOSE Our goal was to describe the CT findings of aberrant left gastric vein (ALGV) and to evaluate the clinical significance of this vein. METHOD Four patients in whom ALGVs were demonstrated by helical CT were examined. Each patient had either intrahepatic cholangiocarcinoma, cirrhosis with gastric varices, chronic hepatitis, or nonspecific abdominal(More)
PURPOSE To compare dynamic incremental computed tomography (CT) with other techniques in detecting and evaluating small hepatocellular carcinomas (HCCs). MATERIALS AND METHODS Two-phase (early vascular and parenchymal) dynamic incremental CT of the entire liver and ultrasonography (US) were performed in 184 patients with chronic liver disease. Thirty(More)
PURPOSE Our goal was to differentiate between early homogeneously enhancing hepatocellular carcinoma (HCC) and hemangioma by two-phase CT. METHOD Two phase images of 51 HCCs and 28 hemangiomas showing homogeneous high attenuation in the first series (arterial dominant phase) were reviewed. Enhancement patterns of the lesions in the second series(More)
PURPOSE To determine the prevalence and possible cause of pseudolesions in the left hepatic lobe around the falciform ligament at hepatic helical computed tomography (CT). MATERIALS AND METHODS Portal venous-dominant CT scans of 472 consecutive patients were reviewed. CT of the left hepatic lobe was performed after injection of contrast material into the(More)
Primary paraovarian cancer is a rare tumor occurring in the female pelvis. Magnetic resonance imaging features of paraovarian cancer have not been previously reported. In the present report, we describe a case of paraovarian cancer coexisting with cancer of the fallopian tube and the magnetic resonance features.
