文摘目的基于2018版肝脏影像报告及数据系统(LI-RADS v2018),探讨CT及MRI对乙肝肝硬化背景下长径≤3 cm肝细胞性肝癌(hepatocellular carcinoma,HCC)的诊断价值。材料与方法回顾性分析本院2009年1月至2020年12月间73例有乙肝肝硬化病史且经病理证实占位长径≤3 cm HCC的患者,并在1个月内行CT及MRI检查。依据LI-RADS v2018,对每个病灶的CT及MRI图像的主次要征象及分级进行评估及比较。比较CT及MRI对长径≤3 cm HCC的诊断准确率。结果主要征象中的"包膜"表现在MRI中识别率高于CT(P<0.001)。次要征象中的扩散受限征象(86.3%)在MRI中具有最高识别率,而在CT的次要征象中马赛克征(25.0%)的识别率最高。CT及MRI检查的LI-RADS v2018分级差异有统计学意义(P<0.001)。MRI在以LR-4/5标准诊断HCC的准确率优于CT(P=0.046)。结论基于LI-RADS v2018,MRI检查对长径≤3 cm HCC的部分征象的识别率及HCC诊断准确率均高于CT检查。
