Objective:To investigate the MDCTA findings and clinical epidemiology of carotid Artery atherosclerostic plaques by analyzing 150 cases with atherosclerostic plaques.Methods:150 cases with atherosclerostic plaques underwent large extent MDCTA and CDS examination,29 of which underwent DSA examination.Results:317 plaques shown by the images were distributed in different areas as the following:the initiated part of carotid artery 37,the common carotid artery 28,carotid artery bifurcation 173,the internal carotid artery 44 and the external carotid artery 35.The incidence of slight,medium,high degree of stenosis and occlusions were 30.95%,49.41%,16.96% and 3.87% respectively.The incidence of calcification occurred in the carotid artery artery bifurcation level was 64.7% with slight or medium degree of stenosis.In contrast,beyond the bifurcation,the incidence of calcification was 23.9% with medium and high degree of stenosis.The irregular and ulcer of the plaque has no obvious difference among them.Conclusion:Atherosclerostic plaques in carotid artery are distributed in any areas with the difference between the incidence of soft plaque and the degree of stenosis.Large extent carotid artery MDCTA is valuable in the diagnosis of atherosclerostic plaques.
