BACKGROUND Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) is an MRI contrast agent with perfusion and hepatoselective properties. The purpose of the study was to examine uptake of Gd-EOB-DTPA in the hepatobiliary phase in hepatocellular carcinoma (HCC). METHODS A retrospective analysis of 22 patients with HCC who underwent(More)
PURPOSE To prospectively compare combined radiofrequency ablation and transcatheter arterial chemoembolization (TACE) with radiofrequency ablation alone for the treatment of small (< or =3 cm) hepatocellular carcinomas (HCCs). MATERIALS AND METHODS The ethics committee of the study institution approved the study protocol. Written informed consent was(More)
PURPOSE The aim of this study was to evaluate image quality of 3D MR cholangiography (MRC) using high sampling efficiency technique (SPACE) at 3T compared with 1.5T. METHODS AND MATERIALS An IRB approved prospective study was performed with 17 healthy volunteers using both 3 and 1.5T MR scanners. MRC images were obtained with free-breathing(More)
OBJECTIVE To compare the accuracy of gadolinium ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI with that of diffusion-weighted MRI (DWI) in the detection of small hepatic metastases (2 cm or smaller). METHODS Forty-five patients underwent abdominal MRI at 3 T, including T1-weighted imaging (T1WI), T2-weighted imaging (T2WI),(More)
OBJECTIVE The purpose of this study was to evaluate the effectiveness of the periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER [BLADE in the MR systems from Siemens Medical Solutions]) with a respiratory compensation technique for motion correction, image noise reduction, improved sharpness of liver edge, and image(More)
PURPOSE The aim of this study was to use intravoxel incoherent motion diffusion-weighted imaging to discriminate subtypes of renal neoplasms and to assess agreement between intravoxel incoherent motion (perfusion fraction, fp) and dynamic contrast-enhanced magnetic resonance imaging (MRI) metrics of tumor vascularity. SUBJECTS AND METHODS In this Health(More)
PURPOSE To evaluate motion correction effect and image quality in the upper abdomen with the periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) (BLADE) and parallel imaging acquisition technique. MATERIALS AND METHODS A total of 50 consecutive patients underwent abdominal MR imaging. Fat-saturated T2-weighted turbo(More)
Solid pseudopapillary tumors (SPTs), predominantly affecting young women, are rare pancreatic tumors. It is reported that imaging features of SPT are solid and cystic components, and there is intratumoral hemorrhage and calcification. However, findings of positron emission tomography (PET) using F-18 fluorodeoxyglucose (FDG) with pathologic correlation have(More)
OBJECTIVE To compare 8-detector row helical computed tomography (CT) findings with histopathology in patients with hepatocellular carcinoma (HCC) who had undergone living-donor liver transplantation (LDLT). MATERIALS AND METHODS This institutional review board-approved prospective study was performed between February 12, 2003 and November 12, 2004; of the(More)
AIM   Transcatheter arterial chemoembolization (TACE) is an established treatment for unresectable hepatocellular carcinoma (HCC). However, it is unclear which chemotherapeutic agent should be selected for TACE. The aim of this study was to compare the efficacy of cisplatin (CDDP) with that of epirubicin (EPI) in TACE for patients with unresectable or(More)
