To compare the findings of pancreaticobiliary duct dilation due to pancreatic carcinoma and chronic pancreatitis by magnetic resonance cholangiopancreatography (MRCP).
MRCP findings in 28 cases of pancreatic carcinoma and 42 cases of chronic pancreatitis were retrospectively analyzed. Both plain MR and MRCP examinations were performed in all the cases after oral Gd-DTPA dilution.
MRCP in the patients with pancreatic carcinoma displayed dilated pancreatic duct with smooth and regular caliber (n=16, 72.7%), dilated common biliary duct with abrupt rupture in most cases (n=18, 90%) and intra- and extra-hepatic cholangiectasis (n=12, 42.8%), and the double-duct sign (n=19, 86.5%). In the patients with chronic pancreatitis, MRCP identified irregular dilation of the pancreatic duct across the whole segment of the lesion (n= 20, 60.6%), taper of the dilated common bile duct (n=8, 80%), stones within the pancreatic duct (n=5, 11.9%), and pancreatic pseudocsyt within the pancreatic duct (n=21, 50%).
Cholangiopancreatographic findings of pancreaticobiliary duct dilation are of great value in distinguishing pancreatic carcinoma from chronic pancreatitis.
通过磁共振胰胆管造影（MRCP）比较胰腺癌与慢性胰腺炎所致胰胆管扩张的表现。
回顾性分析28例胰腺癌和42例慢性胰腺炎患者的MRCP表现。所有病例均在口服稀释的钆喷酸葡胺（Gd-DTPA）后行平扫磁共振成像（MR）及MRCP检查。
胰腺癌患者的MRCP表现为胰管扩张，管径光滑规则（16例，72.7%）；胆总管扩张，多数病例呈突然中断（18例，90%）；肝内、外胆管扩张（12例，42.8%）；双管征（19例，86.5%）。慢性胰腺炎患者的MRCP表现为病变全段胰管不规则扩张（20例，60.6%）；扩张的胆总管呈逐渐变细（8例，80%）；胰管内结石（5例，11.9%）；胰管内胰腺假性囊肿（21例，50%）。
胰胆管扩张的胰胆管造影表现对鉴别胰腺癌与慢性胰腺炎具有重要价值。
