摘　　要：目的本研究旨在通过对比多排螺旋CTA测量颈动脉壁厚度与超声测量内中膜厚度的相关性,探讨颈部动脉CTA检查是否可以成为评估颈动脉内膜-中膜厚度的新方法。方法收集在我院行颈动脉超声检查及颈动脉CTA检查的老年患者39例。通过CT后处理技术进行颈动脉壁厚度评估,通过超声测量评估颈动脉内膜-中膜厚度,并评估两种方法的一致性。结果CTA测量颈动脉壁厚度的范围为0.49mm-1.21mm,均值为(0.85±0.19)mm。超声测量内中膜厚度的范围为0.51mm-1.25mm,均值为(0.88±0.19)mm。CTA评估颈动脉壁厚度与超声测量颈动脉内中膜厚度具有良好一致性,一致性界限的范围为-0.08~0.13,偏倚为0.025mm,CTA测量颈动脉壁厚度与超声测量颈动脉内中膜厚度的直线相关统计分析表明其结果具有高度的正相关性,其相关系数为r=0.923。结论CTA评估老年患者颈动脉管壁厚度不仅可以取得超声测量颈动脉内膜中膜的效果,还能够提供更多的诊断信息。Objective To assess the agreement between multidetector row computed tomography angiography(MDCTA)in measuring carotid artery wall thickness(CAWT)and color Doppler ultrasound(CD-US)in measuring intimae-media thickness(IMT).Methods Thirty-nine patients were retrospectively analyzed using a 256-detector MDCTA and a CD-US scanner.Continuous data were described as the mean value±standard deviation,and Pvalue<0.05was considered significant.Bland-Altman statistics were employed to measure the agreement between MDCTA and CD-US.Results IMT ranged from 0.49to 1.21mm,with a mean value of 0.85mm.CAWT ranged from 0.51to 1.25mm,with a mean value of 0.88mm.We observed an excellent agreement between CD-US and MDCTA in the evaluation of the common carotid artery thickness,with a bias between methods of 0.025mm.Pearson correlation coefficient was 0.923.Conclusion We conclude that there is an excellent correlation between CAWT and IMT measurements obtained with the MDCTA and CD-US.
