Abstract：Objective To evaluate the value of superb micro-vascular imaging(SMI) on neovascularization of carotid athero-sclerosis plaque contrast by contrast-enhanced ultrasound (CEUS). Methods A total of 69 patients with carotid atherosclerotic plaques accepted color Doppler flow imaging(CDFI) and SMI. Of them,35 cases were examined by contrast-enhanced ultrasound (CEUS) and ultrasonic features(including the number of carotid atherosclerotic plaques,position,thickness,echo,surface and ulcer,and carotid artery stenosis were recorded. Assessment of carotid artery plaque neovascularization (including the position, shape,number,evaluation and consistency of SMI and CEUS) obtained by SMI and CEUS respectively were documented and ana-lyzed. The neovascularization within the plaque was categorized as grade 0 to grade 2. Results SMI:The score of 18 cases about neovascularization in plaque were 0,26 cases were 1,25 cases were 2;CEUS:The score of 7 cases about neovascularization in plaque were 0,13 cases were 1,15 cases were 2. It had good consistency between SMI and CEUS(kappa=0.689,P <0.05). Conclusion In detecting carotid artery plaque neovascularization,it has good consistency between SMI and CEUS. SMI can be used as first choice in detecting carotid plaques neovascularization.
