Abstract
- Objective To explore the diagnostic value of superb micro-vascular imaging (SMI) for patients with vulnerable plaque of carotid artery. Methods Totally 69 patient with carotid hypoechoic or predominantly hypoechoic plaque (108 plaques),which were identified by conventional ultrasound,underwent SMI and contrast-enhanced ultrasound (CEUS). Based on the scores of CEUS and SMI (0,1,and 2 points),the consistency of SMI and CEUS in detecting plaque neovascularization was assessed. Results SMI could more clearly display the profile and morphology of the plaques than conventional ultrasound. SMI showed that there were neovascularization in 75 plaques,and CEUS showed that there were neovascularization in 76 plaques;the number of scoring consistency in the plaque neovascularization under SMI and CEUS was 90,suggesting these two results were highly consistent (Kappa value=0.748). There were 6 ulcerated carotid plaques detected by SMI,and the same 6 ulcerated carotid plaques were detected by CEUS,showing complete consistency. Of these 108 plaques,55 caused stenosis of the lumen,and SMI showed there was no correlation between plaque neovascularization and stenosis of the lumen caused by plaques (P=0.473). Conclusion SMI can clearly display the morphology and outline of the plaques and the plaque neovascularization. Therefore,it can be used for evaluating plaque vulnerability.
