原发性胆囊癌的MRI诊断

MRI Diagnosis of Primary Gallbladder Carcinoma and Differential Diagnosis(Analysis of 83 Cases)

目的:分析原发性胆囊癌的MRI表现。方法:回顾性分析经手术病理证实的83例原发性胆囊癌的MRI资料。结果:83例胆囊癌MRI术前诊断的符合率为91.57%(76/83)。原发性胆囊癌在MRI上分4型:胆囊壁增厚型(33例),乳头结节型(16例),肿块型(24例),混合型(壁增厚及结节)(10例);合并慢性胆囊炎及胆囊结石的有65例,占(78.31%)。结论:MRI对胆囊癌临床诊断及治疗能提供有价值指导资料。

Objective： To study the MRI features of primary gallbladder carcinoma. Methods： MRI manifestations of 83 cases with gallbladder carcinoma confirmed by operation and pathology were reviewed retrospectively. Results： The preoper ation diagnostic accuracy rate with MRI for 83 cases of ballbladder carcinoma was 91.57% （76/83）. Four patterns of gallbladder carcinoma were found on MRI： wall thickening （33 cases）, papillary nodular type （16 cases） , mass type （24 cases） and mixed type （wall thickening and nodules） （10 cases）. Combined chronic cholecystitis and cholecystolithiasis were found in 65 cases （78.31% ）. Conclusion： MRI is of significant value in gallbladder carcinoma diagnosis, since it can provide valuable information for clinical diagnosis and treatment.
