This study was to compare the category of unenhanced combined contrast enhanced MR imaging (MR) and Multiphasic CT (CT) in the diagnosis of HCC based on LI-RADS 2014 in patients with cirrhosis induced by HBV infection. We restropectively collected patients who had both undergone CT and MR imaging within 30 days and had pathologically proved HCC. A radiologist using LI-RADS 2014 recored the imaging features and the category of all the lesions. The result showed that MR showed higher LI-RADS category compared with CT, and had better ability for the showing of some imaging features. Thus, we concluded that MRI can elevate the LI-RADS category and is recommended in the initial evaluation of suspected HCC priority to CT.
