      【摘要】 目的 比较基于肝脏影像报告和数据系统 2018版(LI-RADSv2018)分类中肯定的肝细胞癌(LR-5)和具有肿瘤血管浸润的肝细胞癌(LR-TIV-HCC)患者病变强化包膜的发生率及完整性，探讨肝细胞肝癌(HCC)强化包膜预测肿瘤血管浸润的价值。方法 回顾性分析 2018年 7月至 2021年 3月在阳西总医院人民医院影像诊断中心行CT或MR增强扫描的55例乙型肝炎患者的临床和影像资料，按LI-RADSv2018分类分为LR-5组22例，LR-TIV-HCC 组33例，比较两组患者病变强化包膜及病变大小、数目的差异。结果 LR-5组患者中，有完整强化包膜16例，包膜发生率为72.73%，无强化包膜或包膜不完整6例，占27.27%，而LR-TIV-HCC组患者均无完整强化包膜，其中 15例无明确强化包膜，18例包膜不完整，两组患者病变强化包膜比较，差异有统计学意义(P<0.05)；LR-TIV组患者的多发病变例数明显多于LR-5组，差异有统计学意义(P<0.05)，而两组患者病变大小比较差异无统计学意义(P>0.05)。结论 肝细胞癌病变强化包膜、数目对肿瘤血管浸润的预测具有一定价值。

【Abstract】 Objective To compare the incidence and integrity of enhanced capsule of LR-5 and LR-TIV hepa-tocellular carcinoma (HCC) based on Liver Imaging Reporting and Data System Version 2018 (LI-RADS v2018), and toexplore the value of enhanced capsule in predicting vascular infiltration in HCC.Methods The clinical and imaging da-ta of 55 patients who underwent contrast-enhanced CT or MR scanning from July 2018 to March 2021 in the Imaging Di-agnosis Center, People's Hospital of Yangxi General Hospital were retrospectively analyzed. According toLI-RADSv2018, the patients were classified as LR-5 group (n=22) and LR-TIV-HCC group (n=33). The enhanced cap-sule, size, and number of lesions were compared between LR-5 group and LR-TIV-HCC group. Results In LR-5group, there were 16 cases with complete enhanced capsule (72.73%, 16/22) and 6 cases without enhanced capsule orwith incomplete capsule (27.27%, 6/22). In LR-TIV-HCC group, all the 33 patients had no complete enhanced capsule,among which 15 cases had no clear enhanced capsule and 18 cases had incomplete enhanced capsule. There were statisti-cally significant difference in enhanced capsule between LR-5 and LR-TIV-HCC groups (P<0.05). The number of pa-tients with multiple lesions was significantly higher in LR-TIV-HCC group than LR-5 group (P<0.05), and there was nostatistically significant difference in lesion size between the two groups (P>0.05). Conclusion The enhanced capsule oflesions and number has certain value in the prediction for vascular infiltration in hepatocellular carcinomas.
