磁共振胰胆管成像的临床应用(71例分析)

Clinical Application of Magnetic Resonance Cholangiopancreatography(Analysis of 71 Cases)

目的 探讨磁共振胰胆管成像（ＭＲＣＰ）技术在胰胆道系统疾病中的应用价值。 方法 ７１ 例患者经ＣＴ 或Ｂ超检查疑有胆总管及胰腺疾病的患者，采用高级转换快速自旋回波系列行ＭＲＣＰ检查，图像经三维最大信号强度投影（ＭＩＰ）后处理。 结果 ＭＲＣＰ能清楚显示胰胆形态，胰胆管良恶性病变具有特征性表现，定位准确率１００％ ，定性准确率为８８．７％ 。 结论 ＭＲＣＰ是一种无创伤的检查技术，定位和定性准确率高，在胰胆管疾病的诊断方面，具有重要的临床价值。

To evaluate the clinic value of magnetic resonance cholangiopancreatography(MRCP) in diagnosis of pancreaticobiliary duct diseases \ Methods\ 71 cases suspected the pancreaticobiliary duct diseases in CT or ultrasound examination were performed with MRCP using fast advanced spin echo sequence(FASE) \ The resulting slices were then projected for the images composed by standard maximal intensity projection(MIP) methods \ Results\ The malignant or benign lesions of pancreaticobiliary duct may be shown characteristic appearances in MRCP \ The accuracy of MRCP for evaluating the site and the causes of these diseases were 100% and 88 7% respectively \ Conclusion\ MRCP is a noninvasive technique with excellent accuracy in the diagnosis of pancreaticobiliary duct diseases \;
