目的建立一种超声造影（CEUS）的M评分，并将其与CEUS肝脏影像报告和数据系统（LI-RADS）中的LR-M评分进行比较。在2003年11月至2017年12月期间，通过倾向评分匹配选择受试者。基于特定的CEUS特征，通过最小绝对收缩和选择算子正则化回归构建用于预测ICC的CEUS M评分。使用M-评分来开发改进的CEUS LI-RADS。将使用M评分的改良CEUS LI-RADS诊断HCC和ICC的诊断性能与美国放射学会（ACR）使用LR-M的CEUS LI-RADS进行比较。结果ICC最有用的特征如下：界限不清（69.52%），边缘增强（63.81%）、早期洗脱（92.38%）、瘤内静脉（56.19%）、瘤内无强化区边界模糊（57.14%）、明显洗脱（59.05%），均为P
ObjectiveTo develop a contrast-enhanced ultrasound (CEUS) M-score and compare it with LR-M in CEUS Liver Imaging Reporting and Data System (LI-RADS).MethodsWe retrospectively enrolled 105 consecutive high-risk patients with hepatocellular carcinoma (HCC) and 105 with intrahepatic cholangiocarcinoma (ICC). The subjects were selected by propensity score matching between November 2003 and December 2017. A CEUS M-score for predicting ICC was constructed based on specific CEUS features by the least absolute shrinkage and selection operator regularised regression. M-score was used to develop a modified CEUS LI-RADS. The diagnostic performance of the modified CEUS LI-RADS using M-score for diagnosing HCC and ICC was compared with American College of Radiology (ACR) CEUS LI-RADS using LR-M.ResultsThe most useful features for ICC were as follows: poorly circumscribed (69.52%), rim enhancement (63.81%), early washout (92.38%), intratumoural vein (56.19%), obscure boundary of intratumoural non-enhanced area (57.14%), and marked washout (59.05%, all p
