PURPOSE
This study was performed to investigate the interobserver agreement on the detection of carotid artery calcifications on panoramic radiographs.
MATERIALS AND METHODS
This study consisted of panoramic radiographs acquired from 634 male patients of the age of 50 years or older. Having excluded carotids of no diagnostic quality, 1008 carotids from the panoramic radiographs of the patients were interpreted by two oral and maxillofacial radiologists independently for the presence of carotid artery calcifications. Statistical analysis was used to calculate the interobserver agreement.
RESULTS
Interobserver agreement was obtained for 932 carotids (92.4%). Inconsistent interpretation of 76 carotids (7.5%) between the two observers was found. Cohen's kappa value was 0.688 (p<0.001).
CONCLUSION
The probability of a match between the two observers was substantially high.
目的
本研究旨在调查全景X线片上颈动脉钙化检测的观察者间一致性。
材料与方法
本研究纳入了634例年龄在50岁及以上男性患者的全景X线片。排除诊断质量不佳的颈动脉后，两名口腔颌面放射科医生对患者全景X线片上的1008条颈动脉独立解读，以确定是否存在颈动脉钙化。采用统计分析计算观察者间一致性。
结果
932条颈动脉（92.4%）达成了观察者间一致性。发现两名观察者之间对76条颈动脉（7.5%）的解读不一致。科恩kappa值为0.688（p<0.001）。
结论
两名观察者之间匹配的概率相当高。
