高血压性脑出血患者钻孔引流手术后继发性脑梗死的危险因素分析 Risk Factors of Secondary Cerebral Infarction after Trepanation and Drainage in Patients with Hypertensive Intracerebral Hemorrhage

open access: yes, 2023
目的 探索高血压性脑出血(hypertensive cerebral hemorrhage,HICH)患者钻孔引流手术后继发性脑梗死的危险因素。 方法 连续纳入2017年1月—2020年1月在南京同仁医院神经外科行钻孔引流术治疗的HICH患者的临床资料,进行回顾性分析。根据术后1~7 d头颅CT检查是否存在继发性脑梗死,分为继发性脑梗死组和无继发性脑梗死组。通过单因素分析和多因素logistic回归分析筛选出HICH患者继发性脑梗死的独立危险因素,并构建继发性脑梗死的风险预测模型。采用ROC曲线 ...

基于CT的影像组学列线图对布鲁氏菌性脊柱炎和脊柱结核的鉴别价值

open access: yesZhongguo shiyan zhenduanxue
目的基于CT的影像组学列线图鉴别布鲁氏菌性脊柱炎(BS)和脊柱结核(TBS)。方法回顾性分析2018年1月至2023年3月94例布鲁氏菌性脊柱炎及脊柱结核患者的临床资料及CT图像,按照7∶3随机分为训练集和测试集。基于训练集数据,对临床及常规CT征象进行组间差异性分析,并采用多因素logistic回归构建临床模型。基于CT图像提取影像组学特征,并筛选出最优特征计算影像组学评分(Radscore)。联合Radscore、临床特征构建联合模型并绘制列线图。采用受试者工作特征曲线下面积(AUC)、特异性 ...

基于时间序列模型的劣化绝缘子红外热像检测方法

open access: yesDianci bileiqi, 2020
在使用传统红外热像法对绝缘子进行检测时,绝缘子的劣化特征并不稳定,容易导致漏检、误检。针对这个问题,本文提出了时间序列模型与红外热像处理技术相结合的劣化绝缘子识别方法。本方法使用中值滤波与线性平滑滤波优化图像质量;采用OTSU分割法结合钢帽、盘面的形态差异将绝缘子钢帽部分进行提取,实现绝缘子钢帽温度的自动提取;考虑到绝缘子温升受到多因素影响,采用ARIMA时间序列模型对绝缘子串温度时间序列进行拟合,对其温升变化进行预测,从预测结果中找到劣化特征明显的温度曲线进行判别;试验结果表明 ...
