壶腹周围癌的MRI及MRCP征像分析

The MRI and MRCP diagnosis of vater ampulla carcinoma

目的:通过对壶腹周围癌的磁共振胰胆管MRCP和MRI征象特征分析,提高对壶腹周围癌认识水平。方法对经磁共振检查并由病理证实的20例壶腹周围癌的影像特征进行分析归纳总结。结果20例壶腹周围癌共同的MRI表现为低位胆道梗阻和连接区的软组织肿块,不同来源的肿瘤在部位、大小、MRI强化、MRCP表现有不同特征,本组20例壶腹周围癌MRI诊断全部符合,与手术病理结果一致者18例(90%),未明确鉴别诊断者2例(10%)。结论常规 MRI结合MRCP对壶腹周围癌有较高的诊断和鉴别诊断价值。

Objective Use MRCP and MRI characteristic analysis to improve the knowledge and diagnosis of vater ampul a carcinoma.Methods Images of 20 cases of vater ampul a carcinoma were get and analysised.Results 20 cases vater ampul a carcinoma,the MRI appearance is lower biliary obstruction and connective parenchyma mass,dif erent tumors have dif erent MRI strenghth,MRCP appearance,location,and largeness from dif erent sources.Al the 20 cases were in accordance with the diagnosis of MRI standard of vater ampul a carcinoma,and 18 cases(90%)were in agree with pathological diagnosis,2 cases were undefined(10%).ConclusionConventional MRI and MRCP have good diagnosis and dif erential diagnosis value for vater ampul a carcinoma.
