肝纤维化的CT、MR诊断探讨

目的探讨肝纤维化的CT、MR临床诊断情况。方法选取本院2011年4月到2012年10月收治的疑似肝纤维化患者120例，全部给予CT、MR检查以及活检病理检查，对临床诊断资料进行回顾性总结分析。结果CT检查的敏感度为93．18％，CT检查的特异度为71．87％，CT检查的准确度为87．5％；MR检查的敏感度为95．45％，MR检查的特异度为87．5％，MR检查的准确度为93．33％；MR检查在敏感度、特异度、准确度上均优于CT检查，其中特异度和准确度间差异具有显著性，P〈0．05。结论CT检查和MR检查在肝纤维化临床诊断上均具有良好的准确性，是临床动态观察肝纤维化病程演变的重要方法，值得临床推广使用。

CT and MR diagnosis of hepatic fibrosis

Objective To investigate CT and MR diagnosis of hepatic fibrosis. Methods 120 patients with suspected hepatic fibrosis who had been hospitalized during the period of April 2011 to October 2012 were included in this study. All the patients received CT and MR detection and pathological examination by biopsy. The clinical data were retrospectively analyzed. Resul~ The sensitivity was 93.18%, specificity was 71.87%, accuracy was 87.5% for CT examination; whereas the sensitivity was 95.45%, specificity was 87.5%, and accuracy was 93.33% for MR examination. MR detection was superior to CT detection in the sensitivity, specificity, and accuracy, with significant differences in in the specificity and accuracy （P〈0.05）. Conclusions CT and MR examination have better accuracy in the diagnosis of liver fibrosis. They are the important approaches in clinical dynamic observation of development of liver fibrosis and are worth popularizing clinically.
