Abstract: Objective: To assess the values of conventional vascular ultrasound (US) and superb micro vascular imaging (SMI) for diagnosing carotid artery stenosis in relevant patients. Methods: A total of 37 patients of extra cranial carotid stenosis (with 70 blood vessels) treated in our hospital from 2014-08 to 2015-03 were retrospectively studied. Digital subtraction angiography (DAS) examination was used as golden standard, the diagnostic efifcacies for carotid artery stenosis by US and by SMI were compared. Results: The accuracy, sensitivity and specificity for diagnosing carotid stenosis by US were 81.42%, 83.33% and 80.95%; by SMI were 91.43%, 92.16% and 89.47% respectively. Conclusion: US and SMI showed good agreement for diagnosing carotid artery stenosis, while SMI was superior to US for accurately assess the degree of carotid stenosis, it might be used as a more reliable method for evaluating carotid plaque and stenosis in relevant patients.
