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.
Highlights
Until now, no reproducibility study has been proposed; the purpose of this article was to compare inter- and intraobserver agreement among 4 readers in the analysis of CAWT by using MDCTA
We measured CAWT between the leading edge of the opacified lumen vessel and the external visible limit of the artery wall, where it was surrounded by adjacent adipose tissue
Inter- and intraobserver agreement was evaluated by using the Bland-Altman analysis.[22]
Summary
Until now, no reproducibility study has been proposed; the purpose of this article was to compare inter- and intraobserver agreement among 4 readers in the analysis of CAWT by using MDCTA. Four different observers (with 11 years, 10 years, 7 years, and 3 years of experience in CT angiography of carotid arteries) analyzed the datasets and measured the CAWT by using dedicated software. Inter- and intraobserver agreement was evaluated by using the Bland-Altman analysis.[22] A folded empiric cumulative distribution plot
