| 摘 要： | 目的探讨磁共振胰胆管造影（ＭＲＣＰ）诊断恶性胆管梗阻的价值。方法３２例临床怀疑梗阻性黄疸的病人进行了ＭＲＣＰ检查，并全部经手术病理证实。结果ＭＲＣＰ对恶性胆管梗阻部位诊断的准确率为９６．９％，而ＣＴ为８８．５％，超声为７６．０％。ＭＲＣＰ的定性诊断准确率为９６．９％。结论ＭＲＣＰ在恶性胆管梗阻的定位诊断上明显高于超声

| Abstract: | Purpose To evaluate the diagnostic value magnetic resonance cholangio pancreatography in malignant bile duct obstruction. Methods 32 patients with clinically suspected biliary obstruction were examined with MRCP. Results The accuracy of diagnosing location of malignant bile duct obstruction with MRCP was 96.9%, whereas the accuracy of CT and US were 88.5% and 76.0% respectively. The accuracy of diagnosis of nature of malignant bile duct obstruction was 96.9%. Conclusion The accuracy of diagnosis of location of malignant bile duct obstruction with MRCP was superior to US. |
