低场强MRCP对胆囊切除术后综合征的诊断价值

The diagnostic value to the low-field MRCP of postcholecy stestomy syndrome

目的探讨低场强MRI及胆系水成像(MRCP)在胆囊切除术后综合征(PCS)诊断价值。方法对54例胆囊切除术后出现腹痛、黄疸等症状患者进行常规T2WI、T1WI、脂肪抑制T2WI序列及胆系水成像检查。结果54例中胆道结石21例(38.8%),胆道扩张17例(31.4%),胆道狭窄11例(20.3%),残留胆囊或胆囊管余留过长5例(0.09%)。结论MRCP对胆囊术后综合征具有较高的病因诊断符合率,一定程度上可取代创伤性ER-CP检查。

Objective To investigate the performance of low-field strength MRI and MRCP of postcholecy stestomy syndrome diagnosis.Methods 54 cases of post-cholecystectomy syndrome conventional T2WI T1WI fat-suppressed T2WI sequence and MRCP.Results 54 cases were good MRCP images,21 cases of cholelithiasis,17 cases of bile duct expansion,11 cases of biliary stricture,cystic duct stones remaining five cases of long merger.Post-cholecystectomy biliary-enteric anastomosis in 5 cases.Conclusion MRCP has significant diagnosis value to the PCS-related cause of the biliary tract.To a certain extent,MRCP can be used to replace invasive ERCP examination,to provide wealth clinical imaging information and further guiding clinical.
