摘　　要：目的探讨超声与MRI在原发性肝外胆管癌的定性、定位诊断中的临床价值。方法 40例原发性肝外胆管癌,术前行超声和MRI检查,比较两种检查方法的定性、定位诊断的准确性。结果与MRI检查比较,肝外胆管癌超声的检出率和误诊率差异无统计学意义(P>0.05),漏诊率增高(P<0.05);两种检查方法在梗阻部位的诊断上差异无统计学意义(P>0.05)。结论超声检查可作为肝外胆管癌筛查的首选影像学方法,对于临床高度怀疑肝外胆管癌而超声检查呈阴性的病例需联合MRI诊断。Objective To explore the clinical value of qualitative and positioning diagnosis with ultrasonography and MRI in extrahepatic cholangiocarcinoma. Methods Fourty patients with primary extrahepatic cholangiocarcinoma underwent ultrasonography and MRI before operation, the accuracy of qualitative and positioning diagnosis were compared. Results There was no significant difference in the detection rate and misdiagnosis rate of primary extrahepatic cholangiocarcinoma between MRI and ultrasonography （P 〉0.05）, while the missed diagnosis rate of ultrasonography was increased （P〈0.05）. There was no significant difference between the two methods in the diagnosis of obstruction location （P 〉0.05）. Conclusion Uhrasonography can be used as a preferred imaging method for screening primary extrahepatic cholangiocarcinoma. For patients with clinical suspicion of primary extrahepatic cholangiocarcinoma and negative ultrasound report, it is necessary to be further for MRI examination.
