摘要
目的综合评述肝纤维化诊断的各种影像检查方法的应用价值及进展。方法总结超声、CT及磁共振成像在肝纤维化诊断中的表现及最新进展,评价各种方法的特点。结果影像检查不但能显示肝纤维化及肝硬变的形态学改变,还能了解肝脏血流动力学、水分子弥散、生化代谢等反映功能微观方面的信息,尤其是新技术磁共振弹性成像的出现,对肝纤维化诊断意义重大。结论影像学检查,尤其是磁共振功能成像技术,在肝纤维化诊断与鉴别、严重度评价等方面作用重要,具有广阔临床应用前景。
Objective To review the study of noninvasive imaging methods for evaluating liver fibrosis. Methods The current literatures on the use of the ultrasonography, CT and MRI for the evaluation of liver fibrosis were reviewed. The principles, applications and advancement of each imaging methods were described and summarized respectively. The features of the newly developed imaging techniques were also discussed. Results In addition to the morphologic information, the imaging examinations can also provide functional information about the circulation status, diffusion and metabolism features of liver. The potential diagnostic value of MR elastography for liver fibrosis has been addressed. Conclusion The imaging examinations, especially the functional MRI techniques, are reliable noninvasive alternatives for the evaluation of hepatic fibrosis, with bright potentiality for clinical application.
