RESUMO
Objective To review the study of noninvasive imaging methods for evaluating liver fibrosis.Meth- ods 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 re- spectively.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 sta- tus,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.
