Abstract: Objective To investigate the concordance of the main signs in small hepatocellular carcinoma (HCC) (< 3 cm) LI-RADS (2018 edition) among different cases. Methods A total of 193 cases who underwent dynamic enhanced magnetic resonance imaging 1 week to 1 month before surgery and treated by small HCC resection in our hospital from May 2018 to October 2022 were collected. Two doctors will determine whether the patient's lesion exhibits the main signs of the 2018 version of LI-RADS, and the consistency between the them was compared. Results Among the 193 patients, kappa values of the major signs of the 2018 version of LI-RADS judged by 2 observers ranged from 0 to 0.747, and the consistency between observers was positively correlated to the lesion size. Conclusion The consistency between observers of the major signs of 2018 LI-RADS is positively correlated with lesion size.
