The purpose of this study was to evaluate the category modifications and prognosis of LI-RADS 2,2 and 4 observations in cirrhosis on MRI. We retrospectively analyzed 105 LR-2 , 97 LR-3, and 43 LR-4 observations following-up datas. Follow-up duration and category modifications that progressed, remained stable, or decreased were recorded for each observation. Our study showed that LR-2, LR-3 and LR-4 lesions in liver cirrhosis patients present with different natural disease courses and outcomes, the lesions with a higher LI-RADS category have a higher cumulative incidence of progression to LR-5/-TIV lesion, thus demonstrating an increasing risk of developing HCC.
