OBJECTIVES
The purpose of this study was to assess the diagnostic accuracy of the panoramic radiograph in the detection of carotid artery calcification using CT as the gold standard.
METHODS
110 dental patients (average age 65.2 years, range 50-82 years) with both panoramic radiographs and CT scans available were selected for the evaluation of carotid artery calcification. Two oral and maxillofacial radiologists interpreted the panoramic radiographs for the presence of carotid artery calcification. CT scans were independently interpreted by a neuroradiologist.
RESULTS
The accuracy of panoramic radiographs in the detection of carotid artery calcification was 62.3%. The sensitivity and the specificity were 22.2% and 90.0%, respectively.
CONCLUSIONS
Panoramic radiography has a moderate diagnostic accuracy in the detection of carotid artery calcification, but the sensitivity is low.
目的
本研究旨在以CT作为金标准，评估全景X线片检测颈动脉钙化的诊断准确性。
方法
选取110例有全景X线片和CT扫描资料的牙科患者（平均年龄65.2岁，范围50 - 82岁），用于评估颈动脉钙化情况。两名口腔颌面放射科医生解读全景X线片以判断是否存在颈动脉钙化。CT扫描由一名神经放射科医生独立解读。
结果
全景X线片检测颈动脉钙化的准确性为62.3%。敏感性和特异性分别为22.2%和90.0%。
结论
全景X线摄影在检测颈动脉钙化方面具有中等诊断准确性，但敏感性较低。
