摘要: 目的 分析不同观察者之间小肝癌(<3 cm)肝脏影像报告与数据系统[LI-RADS(2018版)]主要征象的一致性。方法 收集2018年5月至2022年10月解放军总医院第五医学中心小肝癌手术切除且于术前1周至1个月内行MR动态增强扫描检查的患者193例,判断病灶是否表现出2018版LI-RADS主要征象,根据病灶大小进行分类对比两名观察者之间的一致性。结果 193例患者中,两名观察者判断病灶2018版LI-RADS主要征象的kappa值介于0~0.747,且随着病灶的增大,观察者之间的一致性逐渐增高。结论 2018版LI-RADS主要征象观察者之间一致性与病灶大小正相关。

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.
