影像学检查在外科肝胆管疾病诊断中的应用与选择

Application and selection of medical imaging techniques in obstructive diseases of hepatic and billiary ducts

目的 比较B超、CT、ERCP和MRCP在肝胆管疾病诊断中的作用,并探讨最优的方法选择。方法 选择68例涉及肝胆管疾病患者,病例包括肝胆管结石、肝门区癌、胰头癌、肝胆管囊肿和十二指肠乳头状瘤等,全部患者行B超检查,其中部分患者分别做CT、MRI和ERCP检查。结果 MRCP在检查成功率、梗阻诊断率和定位定性率方面较其它的方法为高。结论 B超与MR-CP联合应用能在肝胆管疾病定位、定性诊断中取得满意结果。

purpose To compare the diagnostic effects of ultrasound, CT, MRCP, ERCP for better examination selection in hepat - billiary dnetus obstruction. Methods 68 paients with hepat - billiary obstruction underwent ultrosound, CT, MRCP and ERCP. These patients involve stone of hepato - choleductus, tumors of the hepatic portal, carcinomas of the pancreatic head, cysts of hepato - choleductus and papilary tumors of the duodenum. Results MRCP was more preferential than other three methods in showing obstructive position and pathogenesis. Conclusion Combna-tion of ultrasound and MRCP, the satisfied clinic diagnosis can be maked in the diseases of hepat - biliary system.
