基于多参数MRI影像组学术前预测脑膜瘤Ki67表达的研究 附视频
Zhongguo shiyan zhenduanxue目的 探讨基于常规多参数MRI影像组学模型术前预测脑膜瘤的Ki67表达状态的价值。方法 回顾性分析吉林大学中日联谊医院2013年3月至2021年11月305例经术后病理结果确诊为脑膜瘤患者的资料。获取所有患者术前轴位T1WI、T2WI、T2-FLAIR及T1WI增强(T1C)图像，手动标注肿瘤实质区作为感兴趣区(EnHROI),并将病灶边缘向周围膨胀3 mm、5 mm分别得到EnH3mmROI、EnH5mmROI。对图像进行灰度归一化后提取影像组学特征，并使用相关系数法与最小绝对收缩和选择算子 ...
