ABSTRACT
@#【Objective】 We sought to compare ultrasound superb micro- vascular imaging （SMI） and contrast- enhanced ultrasound（CEUS）in the evaluation of carotid plaque neovascularization，and to understand the feasibility of SMI as a method to screen neovascularization of plaque.【Methods】A total of 60 cases，with a total of 109 plaques underwent SMI and CEUS to detect neovascularization of plaque.【Results】SMI and CEUS examination results were consistent in 101 of 109 plaques. The cost of SMI was less than CEUS（￥150 vs. ￥900）. There was significant difference in examination time between SMI and CEUS［（5.0 ± 1.4 vs. 18.5 ± 2.2）min，P < 0.05］.【Conclusion】Preliminary results showed that these two methods have good consistency. SMI also has advantages ：simple ，less time-consuming ，cheap and low risk. It indicates that SMI may be an effective screening method for neovascularization in plaques.
