OBJECTIVES
The objective of this study was to determine whether digital panoramic radiography is a reliable method to detect calcified carotid artery atheromatous plaques (CCAAP) as compared with ultrasonography.
STUDY DESIGN
Digital panoramic radiographs were obtained from 50 patients who also underwent carotid ultrasound examination. The images were interpreted by trained maxillofacial radiologist for the presence or absence of calcified atheromatous plaques. The extent of carotid calcification on carotid ultrasonography was determined by a trained Sonologist, which was considered as the gold standard assessment.
RESULTS
Digital panoramic radiographs had a sensitivity of 76% and specificity of 98.66% in determining CCAAP. There was a high level of agreement between diagnoses, with a kappa value of 0.8.
CONCLUSION
To conclude, digital panoramic radiographs had good sensitivity and high specificity in detecting CCAAP. If properly trained, dentists can detect such plaques and can refer patients to physician for timely medical treatment.
目的
本研究的目的是确定与超声检查相比，数字化全景放射摄影是否是检测钙化性颈动脉粥样斑块（CCAAP）的可靠方法。
研究设计
从50名同时接受颈动脉超声检查的患者中获取数字化全景放射照片。由训练有素的颌面放射科医生对图像进行解读，以确定是否存在钙化性粥样斑块。由训练有素的超声科医生确定颈动脉超声检查中颈动脉钙化的程度，这被视为金标准评估。
结果
数字化全景放射照片在确定CCAAP方面的敏感性为76%，特异性为98.66%。诊断之间存在高度一致性，kappa值为0.8。
结论
总之，数字化全景放射照片在检测CCAAP方面具有良好的敏感性和高特异性。如果经过适当培训，牙医可以检测到此类斑块，并可将患者转介给医生进行及时治疗。
