摘　　要：目的探讨实时三维超声技术在颈动脉粥样硬化斑块定性和定量中的应用价值。方法对22例颈动脉粥样硬化患者进行二维和实时三维超声检查,观察颈动脉及斑块的形态,测量斑块面积以及三维体积,并比较实时三维超声和二维超声测量结果。结果二维及实时三维超声均可以显示斑块的位置、形态及结构,三维超声可显示斑块的立体形态,在钙化斑块也可显示远场的结构。实时三维超声测量斑块最大面积为(0.34±0.16)cm2,二维超声测量斑块最大面积为(0.19±0.12)cm2,测值差异具有统计学意义(P<0.01),两种技术测量的斑块面积存在高度正相关(r2=0.65,P<0.01)。三维超声定量斑块的体积为(0.18±0.11)cm3。结论实时三维超声在颈动脉粥样硬化斑块的定性及定量方面提供了新的方法。Objective To explore the value of real-time three-dimensional （RT-3D） ultrasonography in quantitative and qualitative diagnosis of carotid atheroselerosis. Methods Twenty two patients with carotid atherosclerosis were examined by the RT-3D ultrasonography and the two-dimensional （2D） ultrasonography. The area and the volume of plaques were calculated. Results 2D and RT 3D uhrasonography could display the location, structure and shape of the carotid atherosclerotic plaque. RT-3D ultrasonography could reveal the sterotic structure of the plaque, and display the posterior structure of the calcific plaque which could not be revealed clearly by 2D ultrasonography. The maximal areas of plaques derived from RT-3D ultrasonography and 2D were （0.34±0. 16） cm^2 and （0.19±0. 12） cm^2 respectively （P〈0.01）. There was a high correlation between the maximal areas of plaques by 2D and by RT-3D ultrasonography （r^2= 0.65,P〈0.01）. In addition, RT-3D ultrasonography could measure the volume of plaque （0. 18 ±0. 11） cm^3. Conclusion RT-3D ultrasonography provides a new method in quantitative and qualitative diagnosis of carotid atherosclerosis.
