SMI技术诊断颈动脉粥样硬化斑块内新生血管的生成与斑块声学特性的联系
SMI technique for the diagnosis of neovascularization in carotid plaques and its association with plaque acoustic characteristics
摘要
Abstract
Objective :To evaluate the difference of blood flow imaging with different sonographic characteristics by mi-crovascular imaging technique .Method :A total of 120 patients with carotid plaques in our hospital were selected ,and also 120 plaques on the patients’ body were recorded .Two-dimensional bounce and SMI technology were used to examine the thickness of endometrium in the patients and to analyze the plaque morphology ,acoustic characteristics ,and the formation of new blood flow inside the plaque.Result :The rate of neovascularization in the mixed echo plaques and hypoechoic plaques was significant- ly higher than that in the other two plaques ;there was a difference in blood flow in all types of plaques .The blood flow rate be-tween the plaques with different internal echo was compared ,and we found that there was no significant difference between hy-poechoic plaques and mixed echo plaques ,while ,compared mixed echo plaque with medium echo plaque ,and hyperechoic plaque ,there were significant differences .Conclusion :SMI technique was used to evaluate plaque flow imaging to obtain the following conclusions .The rate of neovascularization in hypoechoic plaques and mixed echo plaques was significantly higher than that in moderate echo plaques and hyperechoic plaques .SMI provides a new possibility for the diagnosis of neovasculariza-tion in atherosclerotic plaques and its manifestation in different echo plaques .关键词
