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 ...

Zhongguo shiyan zhenduanxue, 2010 目的通过一组急性肺脓肿导致的支气管动脉扩张病例的多层螺旋CT影像观察,探讨急性肺脓肿时病变发生部位对肺部侧枝血液循环的影响。方法回顾性分析30例急性肺脓肿的病例影像及临床资料,根据病变的影像分布部位与肺门的关系将病例分为肺门相关组及非相关组,分析支气管动脉扩张在急性肺脓肿中的作用。结果在本组病例中,发生支气管动脉扩张17例,其中肺门相关组15例,非相关组2例,两组间差异有统计学意义（χ2=8.147P=0.002）。结论急性肺脓肿时病变发生部位与肺门关系密切时更易导致肺部侧枝循环开放。
