磁共振胰胆管成像在胰胆管疾病中的诊断价值

The value of MR cholangiopancreatography in diagnosing panoveaticobiliary duct diseases

目的 评价磁共振胰胆管成像在胰胆管疾病中的诊断价值。方法 在SiemensSymphony 1.5T超导型磁共振成像仪上检查患者 6 0例 ,扫描序列为横断位HASTE、冠状位TrueFisp、TurboSEMRCP、HASTEMRCP。 结果 所有图像质量达到诊断要求 ,对胆道梗阻程度的判断和定位诊断准确率为 10 0 %。对结石诊断的准确率为93.3% (2 8/ 30 ) ,对恶性胰胆管梗阻诊断的准确率为 83.3% (15 / 18)。对其他良性梗阻诊断的准确率为 83.3% (10 /12 )。结论 磁共振胰胆管成像是一种无创伤性的有效检查手段 ,能清楚显示正常或异常胰胆管结构 ,定性和定位准确率高 ,能为临床提供重要的诊断资料。

Objective To evaluate the diagnostic value of MR chlangiopancretography in pancreaticobillitary duct diseases. Methods MRCP was performed in 60 cases with Breath hold HASTE,Truefisp,Turbo SE MRCP and HASTE MRCP sequences. Results Images of disgnostic quality were obtained in all cases, The accuracy of MRCP for evaluating the site and the degree were 100%. The accurate rates for calculi,malignant bile duct obstruction and bile duct obstruction was 93.39%,83.3%,83.3% sespectively. Conclusions MRCP is a noninvasive technique for dopicting the normal and abnormal pancreaticobillitary duct, and if had the excellent,accuracy in the determination of the locations and cause.[
