SMI technique for the diagnosis of neovascularization in carotid plaques and its association with plaque acoustic characteristics

Objective:Application of microvascular imaging technique to evaluate the difference of blood flow imaging with different sonographic characteristics.Method:Selection in our hospital with carotid plaques in 120 patients,record 120 plaques on the patient's body, the thickness of endometrium by two-dimensional bounce and SMI technology to the patient, plaque morphology, acoustic characteristics, and the formation of new blood flow inside the plaque were analyzed.Result:The rate of neovascularization in the mixed echo plaques and hypoechoic plaques was significantly higher than that in the other two plaques, there was a difference in blood flow in all types of plaques. The internal echo between different patches of blood flow rate of appearance comparison, we can get a conclusion, no significant hypoechoic plaques and mixed plaques echo difference, compared with mixed echo plaque and medium echo, hyperechoic plaque had significant difference. Conclusion The SMI technique evaluated plaque blood flow imaging to obtain the followingConclusions: the rate of neovascularization in hypoechoic plaques and mixed echo plaques was significantly higher than that in moderate echo plaques and hyperechoic plaques,and SMI provides a new possibility for the diagnosis of neovascularization in atherosclerotic plaques and its manifestation in different echo plaques.
