Abstract

Background: To investigate the level of agreement in the measurement of coronary artery calcification among radiology technicians and radiology specialists.

Materials and methods: This cross-sectional study was conducted on 544 cases in the Radiology Department of Al-Zahra Hospital in Isfahan in 2021. The archives of heart computed tomography scans were reviewed, and coronary artery calcium scores (CACS) reported by radiology technicians and radiologists were marked and compared.

Results: The level of agreement of the score measured by two evaluators in the whole sample is equal to intracluster correlation coefficient = 0.996 (95% confidence interval [CI]: 0.995-0.997) (P < 0.001) and the level of agreement based on calcification categories measured by weighted kappa was 0.968 (95% CI: 0.953-0.982)(P < 0.001), both of which indicate an excellent and significant intensity of agreement.

Conclusion: The results of our study demonstrate a high level of agreement regarding CACS between technicians and radiologists.

调查放射科技术人员和放射科专家对冠状动脉钙化测量的一致程度。

背景：调查放射科技术人员和放射科专家对冠状动脉钙化测量的一致程度。材料与方法：本横断面研究以2021年伊斯法罕Al-Zahra医院放射科544例患者为研究对象。回顾了心脏计算机断层扫描档案，并标记和比较了放射科技术人员和放射科医生报告的冠状动脉钙评分（CACS）。结果：两名评估者在整个样本中测量的评分一致性水平等于集群内相关系数= 0.996(95%可信区间[CI]: 0.995 ~ 0.997) (P < 0.001)，加权kappa测量的基于钙化类别的一致性水平为0.968 (95% CI: 0.953 ~ 0.982)(P < 0.001)，均表明一致性强度非常好且显著。结论：我们的研究结果表明，技术人员和放射科医生对CACS有很高的共识。
