随着微气泡声学造影剂的发展,超声造影 (Contrast-enhanced ultrasound, CEUS) 能实时连续地观察肝脏局灶性病变的血流灌注情况,显著提高了超声诊断肝细胞癌 (Hepatocellular carcinoma, HCC) 的准确性。为规范和统一CEUS的图像采集和影像报告,便于临床医生和影像科医生的临床交流,美国放射学会 (American College of Radiolog...
The American College of Radiology (ACR) endorsed the Liver Imaging Reporting and Data System (LI-RADS) for standardized reporting and data collection of computed tomography (CT) and magnetic resonance (MR) imaging for hepatocellular carcinoma (HCC) in high-risk patients. Originally developed only ...
单因素分析显示,MVI阳性组与阴性组在LI-RADS分级、甲胎蛋白(AFP)水平、造影后与造影前肿瘤面积增加比例、性别分布方面存在差异。多因素分析表明,更高的LI-RADS分级、更高的AFP水平、造影后肿瘤面积的增加是预测MVI的独立风险因素,OR分别为1.675、1.585、1.292。在建模队列中,临床因素模型、超声因素模型、融合因素模型...
LI-RADS 为 HCC 高危人群提供标准化的影像学诊断,将HCC高危人群中发现的每一个肝脏病灶根据提示良恶性可能性的大小分为LR-1到LR-5、LR-M(可能或肯定为恶性,但不是HCC)、LR-TIV(静脉内含瘤),用于指导更细微和个性化的临床决策。
通过Kappa检验评估两种影像学LI-RADS分类的一致性。并对CEUS和CECT/MRI LI-RADS分类不一致的病灶行进一步分析。 结果145个病灶长径为(1.65±0.33)cm。CEUS及CECT/MRI分类为LR-3、4、5、M病灶数分别为16、23、90、16个和25、31、87、2个。CEUS分类为LR-5、M共106个(73.1%),CECT/MRI分类为LR-5、M共89...
目前与美国肝病研究协会(the American Association for the Study of Liver Diseases, AASLD)指南合并在一起修订。LI-RADS分级标准是结合影像学表现,将HCC高危人群的肝脏新生结节进行分类。ACR前后发布了四种影像学LI-RADS系统:普通二维超声(Ultrasound, US);CEUS;CT/MRI诊断和分期;CT/MRI评估疗效。根据LI-RADS的上述...
The Liver Imaging Reporting and Data System (LI-RADS), endorsed by the American College of Radiology (ACR), includes four algorithms: ultrasound (US) LI-RADS for hepatocellular carcinoma (HCC) screening and surveillance, contrast-enhanced US (CEUS) LI-RADS and computed tomography/magnetic resonance...

超声造影LI-RADS 分类在肝细胞肝癌中的应用进展
Herein, we demonstrate that the refined definition of the typical contrast enhanced ultrasound pattern of HCC introduced by the Liver Imaging Reporting and Data System (LI-RADS®) practically abolishes the risk of misdiagnosis of other malignant entities (e.g. cholangiocarcinoma) for HCC with ...
