Abstract
The purpose of this work was to compare inter- and intraobserver agreement in the analysis of CAWT by using MDCTA. The CAWT in 35 patients was quantified by 4 observers. Bland-Altman statistics were used to measure the agreement between observers. The results of our study demonstrated that the CAWT measured by using MDCTA shows a good reproducibility between observers by considering inter- and intraobserver agreement.
摘要
这项工作的目的是比较使用 MDCTA 分析 CAWT 的观察者间和观察者内的一致性。通过 4 位观察者对 35 例患者的 CAWT 进行了定量分析。采用 Bland-Altman 统计分析来衡量观察者之间的一致性。我们的研究结果表明，考虑到观察者间和观察者内的一致性，使用 MDCTA 测量的 CAWT 具有良好的可重复性。
