| 摘 要： | 目的比较高分辨率超声和超声射频信号血管内中膜分析(QIMT)技术测量儿童颈动脉内中膜厚度(IMT)的可靠性。方法两名超声科医师分别应用操作者徒手测量法和QIMT技术测量32名儿童的双侧颈动脉IMT。结果 QIMT技术和操作者徒手测量法测量颈动脉IMT的均差(MD),在检查者间比较,左侧为-0.00和-0.09 mm,右侧为-0.01和-0.11 mm;组内相关系数(ICC)在检查者间比较,分别为左侧0.808和0.335;右侧0.875和0.415。Bland-Altman分析显示,QIMT技术有较好的一致性,优于操作者徒手测量法。结论在规范的测量条件下,QIMT技术的检查结果具有较好的一致性,可准确测量颈动脉IMT。

| Abstract: | 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... |
