摘　　要：目的:探讨研究MRCP对梗阻性黄疸的诊断价值。方法:对43例经手术病理证实的结石、良性狭窄、壶腹癌、胰头癌、胆管癌的梗阻性黄疸患者进行MRCP检查。结果:结石11例,良性狭窄2例,先天性胆总管囊肿1例,壶腹癌5例,胰头癌7例,胆管癌15例,胆囊癌2例。MRCP能清晰地显示正常胰胆管树的结构,能直观显示胰胆管扩张和梗阻的部位、形态、范围,其检出率和定位率为100%,定性诊断率为98%。结论:MRCP对梗阻性黄疸定位、定性诊断准确,特别对结石的诊断,结合原始图像有特异性,能清楚显示梗阻部位、梗阻原因、病变形态、病变与周围关系及病变性质。Objective： To study the diagnostic value of obstructive jaundice with magnetic resonance cholangiopancreatography. Methods： Forty-three cases with pathologically proved gallstone, benign bile duct＇s stenosis, ampullary carcinoma, carcinomas of head of pancreas and carcinoma of bile duct were examined by MRCP. Results： The examined result of MRCP was eleven gallstone, two benign bile duct＇s stenosis, one with congenital choledochal cyst, five ampullary carcinoma, seven carcinomas of head of pancreas, 15 carcinoma of bile duct, two carcinoma of gallbladder. MRCP depicted clearly the normal pancreaticobiliary duct and showed directly the position and morphology of the obstruction or dilatation of the pancreaticobiliary duct . The accuracy of displaying obstructive level was 100% and the accuracy of judging the nature of obstructive lesion was 98%. Conclusion： The MRCP could display the location and nature of bile duct obstruction accurately, and the relationship with surrounding structure. With source images ,it was very special for diagnosis of gallstone.
