The application value of superb micro_vascular imaging in the evaluation of carotid artery plaque neovascularization

目的 :探讨超微血管成像(SMI)在颈动脉斑块新生血管评价中的应用价值。方法 :对30例颈动脉斑块患者行SMI及超声造影,并行对比研究。结果:30例共发现79个斑块,其中等回声斑块25个,混合回声斑块35个,溃疡斑块19个;SMI检出新生血管72个,超声造影检出新生血管74个;经Kappa检验,2种方法检测新生血管一致性良好(K=0.708,P<0.01)。结论:SMI可有效检出颈动脉斑块内新生血管,进而对斑块的稳定性作出客观评价。

Objective：Discussion on the application value of superb micro-vascular imaging in the evaluation of the carotid artery plaque neovascularization. Methods：30 patients with carotid artery plaque were compared with SMI and contrast-enhanced ultrasound. Results：79 plaques were founded in 30 patients,including 25 echo plaques,35 hybrid echo plaques and 19 ulcer plaques. 72 neovascularization were detected by SMI,74 neovascularization were detected by CEUS. By Kappa test,K=0.708,P〈0.01. Conclusion：two methods for detection of neovascularization has a good consistency,SMI technology can be effectively de-tected neovascularization within carotid artery plaque,to make an objective evaluation on stability of plaque.
