Accuracy of MRCP is comparable with that of ERCP. Regardless of modality, a lengthy segment of extrahepatic bile duct stricture with irregular margin and asymmetric narrowing suggests cholangiocarcinoma, and a short segment with regular margin and symmetric narrowing suggests benign cause.

Tumors with a high pretreatment K(trans) value tended to respond better to CCRT than did tumors with a low pretreatment K(trans) value. Perfusion CT may be used to predict tumor response to CCRT in patients with pancreatic cancer. This might aid in development of a tailored approach to therapy in these patients.

UNLABELLED: This study evaluates the performance of diffusion-weighted magnetic resonance imaging (DWI) for the detection of hepatocellular carcinoma (HCC) in pre-liver transplantation patients, compared and combined with contrast-enhanced T1-weighted imaging (CET1WI), using liver explant as the standard of reference. We included 52 patients with cirrhosis (40 men, 12 women; mean age, 56 years) who underwent DWI and CET1WI within 90 days of liver transplantation. Magnetic resonance images were a

AIMS: This study's purpose was to identify the neural substrates and mechanisms responsible for craving among subjects with alcohol use disorders (AUDs) using functional magnetic resonance imaging (fMRI). METHODS: Alcohol abusers with AUD (n = 9) and demographically similar non-abusers (n = 9) participated in this study. After given 5 cc of alcohol, subjects were exposed to different types of stimuli [i.e. alcohol, non-alcoholic beverage, and visual control pictures and one rest (cross-hair)]. C

In the assessment of acute cholecystitis, US is superior to MR cholangiography in the evaluation of gallbladder wall thickening. However, MR cholangiography is superior to US in the depiction of cystic duct and gallbladder neck calculi at the evaluation of cystic duct obstruction.

In 2003, 13 isolates of iridovirus were obtained from cultured flounders Paralichthys olivaceus during epizootics in Korea. The full open reading frames (ORFs) encoding the major capsid protein (MCP) (1362 bp) from the 13 flounder iridoviruses (FLIVs) were sequenced and the deduced amino acid sequences were phylogenetically analyzed. Phylogenetic analysis of the MCP revealed that all 13 FLIVs were the same species as rock bream iridovirus (RBIV), red sea bream iridovirus (RSIV), and infectious s

Using MPR images enables more accurate preoperative T staging of gastric cancer, but not for N staging in either classification system.

MR cholangiography is superior to direct cholangiography for accurate topographic evaluation of recurrent pyogenic cholangitis because it is able to depict all of the biliary tree, despite obstruction or stenosis.

PURPOSE: To quantify liver T1 relaxation times before and after oxygen inhalation in patients with and without liver cirrhosis using a 3 Tesla (T) MRI. MATERIALS AND METHODS: Institutional Review Board approval and written informed consent were obtained. Ninety-two noncirrhotic patients and 87 patients with hepatitis B viral liver cirrhosis (72 Child-Pugh class A and 15 Child-Pugh class B or C) underwent MRI with a 3.0T system before and after the supply of 100% oxygen at a rate of 15 L/min by m

OBJECTIVE: To evaluate the imaging and clinical findings of pathologically proven sarcomatoid hepatocellular carcinoma (HCC) in 11 cases. METHODS: We retrospectively reviewed the imaging findings and clinical features of 11 patients with pathologically proven sarcomatoid HCC at 2 university-based tertiary institutions from July 1997 to June 2006. RESULTS: The most common gross morphologies of sarcomatoid HCC were massive expanding pattern (n = 6 [54%]) or multinodular confluent (n = 5 [46%]) wit

Combined conventional T2-weighted and MnDPDP-enhanced T1-weighted MR cholangiography may eliminate the use of other studies for the imaging of biliary complications after cholecystectomy if this preliminary data can be verified in a larger study.
