原发性胆囊癌102例MRI诊断价值分析

The Value of MRI in Diagnosis of Primary Gallbladder Carcinoma(102 cases)

目的分析原发性胆囊癌的MRI表现,以提高胆囊癌诊断价值.方法对102例资料齐全的原发性胆囊癌MRI资料进行回顾性分析,所有病例均行常规的磁共振平扫、增强及弥散加权成像.结果肿块型54例、腔内型26例,胆囊壁增厚型20例,T1WI呈稍低信号,T2WI呈稍高信号,增强扫描延时强化明显,DWI呈高信号,合并肝脏局部浸润38例,肝脏转移31例,胆囊结石87例,淋巴结转移64例,胆总管梗阻57例,腹水13例,胆胰管汇合异常5例.结论 MRI对原发性胆囊癌具有较好的诊断价值.

Objective To investigate the MRI features of primary Gallbladder Carcinoma and the diagnostic value of MRI.Methods The MRI manifestations of 102 cases with primary Gallbladder Carcinoma were analyzed retrospectively,All patients who received routine MRI plain and enhancement scan were performed DWI examination.Results There were 54 cases of mass-type,20cases of wall thickening-type,26 cases of intrauterine-type,slightly low signal was showed on T1WI,slightly high signal on T2WI,high signal on DWI.There were 38 cases of hepatic infiltration,31 cases of liver metastasis,87 cases of cholecystolithiasis,64 cases of lymph node metastasis,57 cases of obstruction of common bile duct,13 cases of ascites and 5 cases of abnormal pancreaticobiliary junction.Conclusion MRI has good value in diagnosis of primary gallbladder carcinoma.
