A subset of patients with non-alcoholic fatty liver disease(NAFLD)can progress to nonalcoholic steatohepatitis(NASH).When NASH reaches a fibrosis degree of F≥2 and a NAS score of≥4,this stage of NASH is referred to as fibrotic NASH,which is a key focus in clinical drug trials.Currently,liver biopsy is the gold standard for assessing the histological changes of the liver,but its clinical application is limited by its invasiveness,and therefore,it is of particular importance to develop noninvasive detection methods for fibrotic NASH.This article summarizes the recent research achievements in novel noninvasive diagnostic methods for fibrotic NASH and elaborates on these new diagnostic methods for predicting fibrotic NASH in terms of current status,challenges faced,and prospects for future development.
