PURPOSE: The role of MRI in the detection of cholangiocarcinoma of the common hepatic duct has rarely been described. This study was attempted to ascertain characteristic MR features of cholangiocarcinoma. MATERIALS AND METHODS: The T1(500/30, TRs/TEs) and T2 weighted(200/80, TRs/TEs) MR images were obtained from nine patients with cholangiocarcinoma of the common hepatic duct. The common hepatic lesions were detected in seven cases. MR features of cholangiocarcinoma were analysed according to the signal intensity and associated findings. RESULTS: The seven cases showed lower signal intensity than the surrounding normal liver parenchyma on T1 weighted image. On T2 weighted image, the tumor showed isosignal intensity and hyperintensity in four and three patients, respectively. T2 image also revealed diffusely increased signal intensity in some hepatic lobe or segment in four cases, and Intrahepatic periductal high signal intensity in one case. Other associated MR findings were intrahepatic metastasis, and intratumoral hemorrhage, each noted in a different case. CONCLUSION: T2 weighted Image appears to be effective in the detection of cholangiocarcinoma of the common hepatic duct and evaluation of its associated intrahepatic lesions.

PURPOSE: We report seven cases of pancreas transplantation, first performed in Korea, in the context of postsurgical radiologic studies. MATERIALS AND METHODS: All patients with insulin-dependent diabetes mellitus received transplants from cadevaric(n=6) or living related donor(n=1). Retrospective analysis of 27 US(including 19 Duplex US), two CT, four MRi, and three scintigraphy for these patients was made with surgico-pathological correlation in five cases. RESULT:Of the seven patients, three-month graft survival was five and one-year survival was two. One patient died of abdominal abscess following surgery. US gave the valuable informations regarding the graff swelling, vascular complication, and perigraff fluid collection. RBC bleeding scan was effective of the presence or absence and location of intestinal bleeding. CT was useful in determining the extent and severity of the pancreatitis. MRI gave a little information about functional status of the grafted pancreas. CONCLUSION: The choice of appropriate imaging modalities for postsurgical work up in patients who had pacreas transplantation depends on the clinical conditions of the patients and complications suspected. Further prospective studies appear to be necessary to eatablish the interval and modality choice for early detection of the complication.
