磁共振胰胆管造影对临床疾病的诊断价值

The evaluation with MRCP for the examinatio of clinical diseases

资料与方法:20例病人进行了MRCP检查,使用ELSCIENr 2.0TMR机,2D FSE4740/352MS,用MIP重建图像.结果:7例结石中6例可在MRCP或MRI扫描中发现"充盈缺损"结石信号影.胰头癌MRCP表现为不连接的"双管征",MRI扫描中可见胰头区肿块,壶腹癌表现为相连接的"双管征".胆囊癌表现为在长T1长T2胆汁中等信号的肿块影.讨论:MRCP与MRI结合可对胆道梗阻的病人进行诊断,直径大于5mm的结石多可见到"充盈缺损"的结石信号.胰头癌MRCP上表现为胆总管胰管均扩张但不相连的"双管征",MRI扫描可见胰头区肿块.壶腹癌表现为胆总管胰管均扩张且相连的"双管征".胆囊癌则在水信号中出现等信号的肿块影.先天性胆管囊肿可在术前明确病变的形状及大小,为制定手术方案提供可靠的依据.

MR cholangiopancreatography(MRCP)is a recently developed MR imagings technique.20 cases examined by MRCP are reporeted in this Paper. The sensetivitis for biliary obstruction are high. The MRCP findings Of calculi, pancretic head carcinoma, ampullary carcinoma and gallblader Carcinoma are discussed. Those diseases can be differentiated by MRCP and MRI.
