Abstract

Abstract: This study explored the clinical value of superb microvascular imaging (SMI) in detecting neovascularization in carotid atherosclerotic plaque. A total of 100 patients with carotid atherosclerosis diagnosed by color Doppler carotid ultrasound were selected as the research objects. All the included subjects were examined by SMI and contrast-enhanced ultrasound (CEUS). The results of CEUS were used as the criteria to calculate the consistency between SMI test results and CEUS results. The average thickness of hypoechoic plaques detected by carotid color Doppler ultrasound was (3.22±1.07) mm, the average patch length was (11.60 ±3.31) mm; the average thickness of mixed echo plaques was (3.50 ±1.21) mm, the average patch length was (17.32±4.16) mm, the consistency kappa value between SMI detection grading and CEUS grading was 0.516, P=0.000, Spearman R=0.704, P=0.000, SMI and CEUS had high consistency and correlation. SMI has high consistency and correlation with CEUS results in detecting neovascularization in carotid atherosclerotic plaques, which can be used as a noninvasive, rapid and convenient detection method.
