【摘要】：目的:探討實(shí)時(shí)三維超聲成像(RT-3DU)技術(shù)用于定量分析頸動(dòng)脈粥樣硬化斑塊體積的可行性及準(zhǔn)確性。方法:對(duì)23例頸動(dòng)脈粥樣硬化患者行實(shí)時(shí)三維超聲檢查,對(duì)獲取的35個(gè)斑塊進(jìn)行三維重建,所有斑塊體積由2位超聲醫(yī)師進(jìn)行隨機(jī)雙盲獨(dú)立測(cè)定,1個(gè)月后,由其中1位醫(yī)師再次進(jìn)行測(cè)定。結(jié)果:RT-3DU定量測(cè)量的35個(gè)斑塊的體積為(171±116)mm3。對(duì)于斑塊體積的定量測(cè)量,兩幅Bland-Altman圖中僅見2.9%(1/35)的分散點(diǎn)在一致性界限外,兩幅圖差值均數(shù)的絕對(duì)值與差值均數(shù)為0的基線最大僅相差1.51mm3;對(duì)于管腔體積狹窄率的定量測(cè)量,兩幅Bland-Altman圖中僅見2.9%(1/35)的分散點(diǎn)在一致性界限外,兩幅圖差值均數(shù)的絕對(duì)值與差值均數(shù)為0的基線最大僅相差0.63%;2位觀察者間及觀察者內(nèi)4組數(shù)據(jù)的組內(nèi)相關(guān)系數(shù)均≥0.900,表示觀察者間和觀察者內(nèi)部的一致性較高。結(jié)論:RT-3DU可以立體顯示斑塊的空間形態(tài),斑塊體積及管腔體積狹窄率的定量測(cè)量在觀察者間和觀察者內(nèi)部均有較高的一致性,為動(dòng)脈粥樣硬化斑塊的定性診斷和定量測(cè)量提供了新的檢查手段。
[Abstract]:Objective: to investigate the feasibility and accuracy of real-time three-dimensional ultrasound (RT-3DU) technique for quantitative analysis of carotid atherosclerotic plaque volume. Methods: 23 patients with carotid atherosclerosis were examined by real-time three-dimensional ultrasound. Three-dimensional reconstruction of 35 plaques was performed, and all plaque volumes were measured by two ultrasound physicians at random and double-blind, and one month later, Results the volume of 35 plaques measured quantitatively by 1: RT-3DU was 171 鹵116mm3. For the quantitative measurement of plaque volume, the dispersion points in the two Bland-Altman diagrams were only 2.9 / 35) outside the consistency limit. The maximum difference between the absolute value of the difference mean and that of the baseline with the difference mean 0 is only 1.51mm3.For the quantitative measurement of lumen volume stenosis, the dispersion points of the two Bland-Altman diagrams are only 2.9 / 35) outside the consistency limit. The maximum difference between the absolute value and the average value of the difference between the two maps is 0.63 and 0.63 respectively, and the intra-group correlation coefficients of the four groups of data are all 鈮，
