摘  要:目的研究磁共振胰胆管成像(MRCP)对慢性胰腺炎与胰腺癌的诊断价值。方法分析31例胰腺癌与31例慢性胰腺炎患者的MRCP表现。结果慢性胰腺炎组的MRCP特征包括:(1)胰管多呈现粗细不均扩张(87.1%),可贯通病灶区(93.5%);(2)胆管扩张者占29%;胆总管远端多呈现锥形狭窄(48.4%)或正常(48.4%),突然截断者少见(3.2%);(3)合并胰管结石(25.8%)及假性囊肿(29%)。胰腺癌组的MRCP特征包括:(1)"双管征"多见(67.7%);(2)胰管多呈光滑连续扩张(61.3%),在肿块处突然截断(74.2%);(3)胆管扩张者较多(74.2%),胆总管远端常于胰头或钩突水平突然截断(71%)。结论慢性胰腺炎与胰腺癌的MRCP表现有一定特征,认识这些征象对两者的鉴别诊断有一定帮助。Objective To study the value of magnetic resonance cholangiopancreatography ( MRCP) in diagnosing chronic pancreatitis ( CP) and pancreatic cancer( PC). Methods MRCP findings in 31 cases of CP and 31 cases of PC were analyzed. Results MRCP charac- teristics in CP group included : ( 1 ) irregular dilatation of the pancreatic duct { 87.1% ) , might across the whole segment of the lesion (93.5% ) ;( 2) dilatation of bile duct less( 29% ) ; tapering (48.4% ) or normal (48.4% ) or abrupt interruption {3.2% ) ;( 3 ) stones within the pancreatic duct (25.8%) , pseudocyst (29% ). MRCP characteristics in PC group included: (1 ) doubleduct sign (67.7% ) ;/2) continuous and smooth dilatation of the pancreatic duct distal to tumor (61.3% ) ,abrupt interruption at the site of the tumor (74.2% ) ;( 3) more percentage of bile duct dilatation (74.2% ) ,abrupt interruption of common bile duct at site of tumor (71% ) . Conclusion MRCP characteristics are of vital importance in differenntial diagnosing CP and PC.
