目的:通过分析各种胆管梗阻性病变的MRCP表现,探讨MRCP在胆管梗阻性病变中的诊断价值。方法:回顾性分析116例胆管梗阻性病变,其中慢性胆管炎22例,胆石症49例,肝门胆管癌9例,总胆管癌14,胰头癌21例,胆囊癌切除术后胰头转移1例。结果:71例良性胆管梗阻中,22例为慢性胆管炎,49例胆石症(胆囊结石9例,肝胆管及总胆管结石23例,胆囊及胆管均有结石17例);45例恶性梗阻,9例肝门胆管癌,14例总胆管癌,21例胰头癌,1例胆囊癌切除术后胰头转移。结论:MRCP是一种无创性检查,不需插管,不需造影剂,不需要镇静剂,但由于其空间分辨率不高,需要结合MR横断面T1WI和T2WI检查技术,全面反映梗阻管腔内外情况,综合判断胆道梗阻的性质。
OBJECTIVE: To investigate the MRCP in the diagnosis of biliary obstructive lesions by analyzing the MRCP findings of various obstructive lesions of the bile duct. Methods: One hundred and sixteen patients with obstructive cholangiocarcinoma were retrospectively analyzed, of which 22 were chronic cholangitis, 49 were cholelithiasis, 9 were choledocholithiasis, 14 were cholangiocarcinomas, 21 were pancreatic head cancer and 21 were pancreatic head metastasis after gallbladder carcinoma resection 1 case. Results: Of the 71 patients with benign biliary obstruction, 22 were chronic cholangitis, 49 were cholelithiasis (cholecystolithiasis in 9, hepatobiliary and choledocholithiasis in 23, gallbladder and bile duct in 17) 9 cases of hilar cholangiocarcinoma, 14 cases of cholangiocarcinoma, 21 cases of pancreatic head cancer and 1 case of pancreatic head metastasis after resection of gallbladder carcinoma. Conclusion: MRCP is a non-invasive examination without intubation, without contrast agent, without sedatives, but due to its low spatial resolution, it is necessary to combine the MR T1WI and T2WI MR techniques to fully reflect the internal and external obstruction lumen Situation, a comprehensive assessment of the nature of biliary obstruction.
