CT energy spectrum of carotid plaques in symptomatic carotid stenosis patients
Abstract：Objective To study the accuracy of CT energy spectrum in detecting carotid plaques in symptomatic carotid stenosis patients.Methods Thirty symptomatic carotid stenosis patients with their carotid stenosis ＞70％ detected by CT angiography were included in this study.The energy spectrum curves for regions of interest were obtained by analyzing the carotid plaques and compared with the standard spectrum curves for fiber and fat.The pathology of carotid plaques was analyzed.The consistency of energy spectrum analysis and pathological analysis of the plaques was compared.Results Of the 32 plaques detected in carotid endarterectomy,3 were type Ⅱ,5 were typeⅢ,6 were type Ⅳ and 18 were typeV.Lipid-rich plaques,plaques with damaged fiber caps and calcified plaques were detected by CT energy analysis and pathological analysis (P＞ 0.05).Conclusion CT energy spectrum can accurately assess the stability of carotid plaques and can thus guide the prevention and treatment of ischemic stroke.
