摘　　要：目的应用实时三维超声（RT-3DU）与CT血管造影（CTA）检测颈动脉斑块体积，评价RT-3DU在颈动脉斑块体积测定方面的临床应用价值。方法对25例患者的32个颈动脉斑块分别进行RT-3DU和CTA检查。RT-3DU采用Qlab软件3DQ插件进行斑块半自动体积测定；CTA采用64层螺旋CT扫描仪和血管分析软件进行斑块体积测定。结果RT-3DU测得斑块体积为（583．09±215．66）mm^3；CTA测定斑块体积为（602．84±182．45）mm^3。两组间测定值差异无统计学意义（P〉0．05），呈显著正相关（r=0．885，P〈0．01）；随斑块体积增大，两组测定值间差异逐渐减小（r=-0．35，P〈0．01）；RT3DU和CTA两种技术测定斑块体积时，观测者间重复性高，分别为2．6％和3．0％。结论RT-3DU可准确测定颈动脉斑块体积，有重要的临床应用价值。Objective To evaluate the clinical value of real-time three dimensional ultrasonography （RT-3DU） in measuring carotid plaque volume in comparison with that of computed tomographic angiography（CTA）. Methods Twenty five patients were examined with two-dimentional ultrasonography, and thirty-two carotid plaques were found. The carotid plaque volumes were measured using RT-3DU and CTA,respectively. RT-3DU images of the plaques were analyzed with Qlab soft system to measure the plaque volume semi-automatically,and the CTA images of the plaques volume were measured by multi-slice spiral CT with blood vessel analysis software. Results There were no significant differences between the plaques volumes measured by RT-3DU and CTA [（583.09 ± 215.66）ram3 vs （602.84 ±182.45）mm^3 , P 〈 0.01],and there was remarkable relationship between the value measured by RT-3DU and that by CTA （r = 0. 885, P 〈0.01 ）. Moreover, the difference of plaques volumes between RT 3DU and CTA decreased gradually with the plaque volume increased（ r = - 0.35, P G0.01）. Conclusions RT-3DU is accurate in measuring plaque volume with great clinical value.
