摘要
目的探讨彩色多普勒超声与磁共振成像(MRI)在原发性肝外胆管癌患者诊断中的应用价值。方法回顾性分析120例原发性肝外胆管癌患者彩色多普勒超声和MRI资料,比较两种检查方法诊断的阳性率、误诊率、漏诊率及梗阻部位准确率。结果两种检查方法对肝外胆管癌诊断的阳性率、误诊率及梗阻部位准确率差异无统计学意义(P>0.05);但彩色多普勒超声检查漏诊率明显高于MRI(P<0.05)。结论彩色多普勒超声可作为肝外胆管癌首选影像学筛查方法,但对于临床高度怀疑肝外胆管癌、而彩色多普勒超声未检出者应加行MRI,以提高诊断的准确性。
Objective To investigate the diagnostic value of color Doppler ultrasound and magnetic resonance imaging （MRI）in the diagnosis of primary extrahepatic bile duct cancer.Methods Retrospective analysis of 120 cases of primary hepatic bile duct malignant tumor patients with color Doppler ultrasound and MRI imaging data and checking method of comparing two diagnostic positive rate,misdiagnosis rate, missed diagnosis rate and obstruction location accuracy. Results There was no significant difference in positive diagnosis rate,misdiagnosis rate and obstructive location diagnosis accuracy of primary malignant tumor of extrahepatic bile duct between two kinds of imaging methods （P〉0.05）.The missed diagnosis rate of primary malignant tumor of extrahepatic bile duct by ultrasound was significant higher than MRI imaging（P〈0.05）.Conclusion Ultrasound can be used as a preferred imaging method for screening primary malignant tumor of extrahepatic bile duct.For patients with clinical suspicion of primary malignant tumor of extrahepatic bile duct and negative ultrasound report,it is necessary to be further for MRI examination.
