Objective To analyze and study of magnetic resonan cecholangio pancreatography (MRCP) in the diagnosis of anatomy variation of cystic duct. Methods In our afifliated hospital in 2011 January~2013year during March, A total of 640 patients treated with MRCP examination. Retrospective analysis and summary of the clinical data of these patients. Results In these patients, including 600 cases showed cystic duct can be clear, for patients with bile duct stones in 58 cases, accounting for 9.7%. 8 patients with cystic duct negative angle into the common hepatic duct;6 patients with cystic duct into the left and right hepatic duct bifurcation;8 patients had low into the hepatic duct parallel;10 patients had low into the common bile duct;6 patients into the common hepatic duct and common hepatic duct on the left and 6 cases;patients with hepatic duct in parallel;10 patients with pronation or supination into the common hepatic duct on the left side;4 cases were short of cystic duct. Conclusion In patients with MRCP, which is a kind of no trauma, and will be able to check method for fast display of the bile duct variation. The patients before the operation details anatomic variation of the biliary tract, reduce the injury in laparoscopic cholecystectomy operation.%目的分析和研究磁共振胆管成像（MRCP）在胆囊管解剖变异中的诊断价值。方法我校附属医院在2011年1月至2013年3月期间，一共收治了640例患者使用MRCP进行检查。对这些患者的临床资料进行回顾性分析和总结。结果在这些患者中，其中有600例患者能够清晰的显示出胆囊管，发生胆囊管变异的患者有58例，占9.7%。8例患者为胆囊管负角度汇入肝总管；6例患者为胆囊管汇入到左右肝管的分叉处；8例患者为低位汇入合并肝总管并行；10例患者为低位汇入到胆总管；6例患者为汇入肝总管的左侧合并肝总管并行；6例患者和肝总管并行；10例患者为旋前或旋后汇入到肝总管的左侧；4例患者为短胆囊管。结论对患者进行MRCP，这是一种没有创伤，并且能够将胆管变异快速显示出来的检查方法。对患者进行手术前了解胆道解剖变异的详细情况，降低在进行腹腔镜胆囊切除手术中的损伤情况。
