摘要	探究T1WI压脂增强静脉期轴位图像纹理分析来鉴别诊断肝内胆管细胞癌（ICC）与肝细胞癌（HCC）价值。方法回顾性分析我院65例病例，病理确诊为肝内胆管细胞癌22例，为训练组，肝细胞癌43例，为测试组。上腹MRI平扫及增强扫描均在术前一周内完成。利用3d-Slicer软件对T1-Vibe压脂序列增强静脉期横断位图像勾画感兴趣区（ROI），提取各个病灶的3D纹理特征共851个，并筛选出有鉴别诊断意义的特征参数。结果通过LASSO回归共筛选出9个有意义的纹理特征，采用logistic回归，进一步筛选出预测模型的3个影像学特征。该模型曲线下面积（AUC）为0.864，提示该模型有鉴别诊断价值。结论基于T1WI压脂增强序列纹理分析来鉴别肝内胆管细胞癌与肝细胞癌，有较好的鉴别诊断价值。
Abstract	Objective: To investigate the value of T1WI lipid compression enhanced axial image texture analysis in the differential diagnosis of intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC). Methods: Retrospective analysis was performed on 65 cases in our hospital. 22 cases were pathologically diagnosed as intrahepatic cholangiocarcinoma, which were in the training group and 43 cases were in the test group. Both plain and enhanced MRI scans of upper abdomen were completed within one week before surgery. 3D-Slicer software was used to sketch the ROI of t1-Vibe enhanced venous transect images, extract a total of 851 3D texture features of each lesion, and screen out characteristic parameters with differential diagnosis significance. Results: Nine significant texture features were screened out by LASSO regression, and three imaging features of the prediction model were further screened out by Logistic regression. The area under curve (AUC) of this model is 0.864, suggesting that this model has the value of differential diagnosis. Conclusion: T1WI lipid compression enhanced sequence texture analysis has good value in differentiating intrahepatic cholangiocarcinoma from hepatocellular carcinoma.
