摘　　要：目的:探讨MRI动态增强联合MRCP在肝外癌性梗阻性黄疸中的临床应用价值。方法:对30例梗阻性黄疸患者在常规MR扫描基础上行MRCP检查及LAVA多期动态增强扫描,观察病变征象并与病理结果对照。结果:30例患者均经病理证实,包括胆管癌15例、壶腹癌5例、胰头癌7例、壶腹周围十二指肠癌1例、胆囊癌2例,其中1例胰头癌漏诊,2例胆管癌和1例壶腹癌误诊为炎症,病灶定性诊断准确率和组织起源诊断准确率分别为86.7%、93.3%。结论:高场MRI动态增强和MRCP技术的联合应用能为肝外癌性胆道梗阻的早期诊断、鉴别诊断提供重要信息,具有很高的临床应用价值。Purpose：To explore the value of combining high field MRI dynamic enhancement and MRCP in the diagnosis of extrahepatic cancerous obstructive jaundice. Methods： Thirty cases of obstructive jaundice were included in this study, MRCP and multi - phase dynamic enhancement were performed following con ventional MRI scans. The manifestions were reviewed and correlated with pathology. Results ： The patho logical diagnosis of the patients were cholangiocarcinoma in 15 cases, ampullary carcinoma in 5 cases, car cinomas of pancreas head in 7 cases, duodenal carcinoma in 1 case, carcinomas of gallbladder in 2 cases. One case of carcinoma of pancreas head was missed. Two cases of cholangiocarcinoma and 1 case of ampullary carcinoma were misdiagnosed as inflammations. The diagnostic accuracy rate of qualitation and location was 86.7% and 93.3%. Conclusion： High field MRI dynamic enhancement combined with MRCP can play an important role in diagnosis and differential diagnosis of extraheoatic cancerous obstructive iaundice.
