摘要
目的 本研究旨在比较人工智能(AI)定量CT辅助诊断系统与定量CT(QCT)在胸部低剂量CT检查时机会性测量腰椎骨密度的一致性.方法 选择2022年6月至2022年12月在我院因各种临床适应症行胸部低剂量CT检查的受检者作为研究对象,应用AI定量CT辅助诊断系统与QCT分别在胸部低剂量CT图像上测量受检者腰椎平均体积骨密度(vBMD),绘制散点图、Bland-Altman图检验二者的关系,计算Pearson相关系数评价其一致性.结果 AI定量CT辅助诊断系统测量vBMD平均值为 116.38±36.07mg/cm3,QCT测量vBMD平均值为115.60±38.07mg/cm3,线性回归分析与Bland-Altman分析显示二者对腰椎骨密度的测量具有良好的一致性,二者呈显著正相关(相关系数r为0.977).不同性别中,Al定量CT辅助诊断系统与QCT对腰椎骨密度的测量亦呈显著正相关.结论 AI定量CT辅助诊断系统与QCT基于胸部低剂量CT机会性测量腰椎vBMD具有高度一致性.
Abstract
Objective To compare the consistency of artificial intelligence(AI)-assisted quantitative CT diagnosis system and quantitative CT(QCT)in opportunistic measurement of lumbar vertebra bone density based on chest low-dose CT examination.Methods Subjects who accepted chest low-dose CT examination from June 2022 to December 2022 for various clinical indications were selected.AI-assisted quantitative CT diagnostic system and QCT were used to measure the average lumbar volume bone mineral density(vBMD).Scatter plot and Bland-Altman plot were drawn to test their relationship,and Pearson correlation coefficient was calculated to evaluate their consistency.Results The Al-assisted quantitative CT diagnostic system exhibited a mean vBMD of 116.38±36.07mg/cm3,and the QCT exhibited a mean vBMD of 115.60±38.07mg/cm3.Linear regression analysis and Bland-Altman analysis showed that the measurement of lumbar vertebrae BMD had good consistency,and there was a significant positive correlation between them(r=0.977).There was also a significant positive correlation between the Al-assisted quantitative CT diagnosis system and QCT in different genders.Conclusion Al-assisted quantitative CT diagnosis system has a good consistency with QCT opportunistic measurement of lumbar vBMD based on low dose chest CT.
