Objective To compare the reliability of high-resolution ultrasound and quality intima-media thickness (QIMT) in evaluation of carotid intima-media thickness (IMT) in children. Methods Bilateral carotid IMT measurements were conducted in 32 children by two doctors of Department of Medical Ultrasound with QIMT and high-resolution ultrasound. Results The mean differences of carotid IMT of QIMT were -0.00 mm for the left and -0.01 mm for the right, and those of high-resolution ultrasound were -0.09 mm for the left and -0.11 mm for the right. The intra-class coefficients of highresolution ultrasound were 0.335 for the left and 0.415 for the right, and those of QIMT were 0.808 for the left and 0.875 for the right. Bland-Altman analysis indicated better interobserver reproducibility for QIMT. Conclusion Under standardized measurement conditions, QIMT may yield favourable interobserver reproducibility, and can measure carotid IMT accurately.
