超声造影肝脏影像报告与数据系统分类标准在M类病变中的应用及进展

Application and progress of the contrast-enhanced ultrasound liver imaging reporting and data system (CEUS LI-RADS) in “M” lesions

肝细胞癌(HCC)和非HCC肝恶性肿瘤在发病机制、生物学行为等方面存在显著差异,超声造影肝脏影像报告与数据系统(CEUS LI-RADS)中M类的存在为两者鉴别提供了新思路。本文介绍了CEUS LI-RADS分类标准在M类病变中的诊断应用情况及进展,认为应用CEUS LI-RADS可以帮助鉴别HCC和非HCC恶性肿瘤,但未来仍需进一步的改进和完善。

Clinically,there are still substantial differences between hepatocellular carcinoma(HCC) and non-HCC liver malignancies in terms of risk factors,pathogenesis,biological behaviors,treatment selections,prognosis,and prevention measurement.The liver imaging reporting and data system(LI-RADS) M(LR-M) classification criteria in the contrast-enhanced ultrasound LI-RADS(CEUS LI-RADS) can help differentiate HCC from non-HCC malignancies.This review discussed and summarized recent advancements in differential diagnosis of HCC from non-HCC using the LR-M criteria and speculated future directions in the field,i.e.,how CEUS LI-RADS distinguish HCC from intrahepatic cholangiocarcinoma,mixed hepatocellular carcinoma cholangiocarcinoma,and liver metastasized and benign tumors.It also discussed differences between CEUS LI-RADS and CT/MRI LI-RADS in diagnosis of liver neoplasms and Sonazoidmodified CEUS LI-RADS in differential diagnosis of HCC from non-HCC.
