多参数磁共振成像联合表观弥散系数直方图分析预测膀胱癌的病理分化

目的探讨多参数磁共振成像联合表观弥散系数（ADC）直方图分析应用于膀胱癌合并其他病理分化类型的预测价值。方法回顾性收集并分析2015年3月至2023年3月就诊于中山大学附属第一医院并经手术病理证实为膀胱尿路上皮癌患者的临床及影像学资料。根据术后病理结果，将患者分为有合并其他病理分化（如鳞状分化、腺样分化等）组及无其他病理分化组。运用倾向性评分匹配的方法，将无分化组患者按年龄及性别与有分化组患者进行两组间1∶1最邻近匹配，两组均入组49例。使用ITK-SNAP软件在ADC对患者病灶全层勾画并将其导入开源软件Pyradiomics提取直方图特征。比较两组间膀胱癌患者的临床、病理及影像参数差异，计算...
