Abstract:
Objective To investigate the correlation between pericarotid fat density(PFD)and carotid plaque CT vulnerability characteristics.Methods The clinical and imaging data of 78 patients were analyzed retrospectively.PFD and subcutaneous neck fat density(SNFD),as well as plaque density,degree of lumen stenosis,and maximum plaque thickness were measured on picture archiving and communication system(PACS),and PFD/SNFD ratio was calculated.The plaques were divided into 4 subgroups according to their composition,namely fatty plaque group,fibrous plaque group,calcified plaque group and mixed plaque group.The groups were divided into no/mild-to-moderate stenosis group and severe stenosis/complete occlusion group according to the degree of stenosis,and the differences between groups were compared for clinical indices,PFD,SNFD and PFD/SNFD ratio,respectively.Results The PFD/SNFD ratio[0.54(0.32,0.72)]in the fatty plaque group was lower than that in the calcified plaque group[0.74(0.56,0.96)],with a statistically significant difference(P=0.005).The PFD/SNFD ratio in the severe stenosis/complete occlusion group(0.51±0.29)was lower than that in the no/mild-to-moderate stenosis group(0.67±0.27)(P=0.001),and the PFD in the severe stenosis/complete occlusion group[-39.75(-61.13,-24.00)]was higher than that in the no/mild-to-moderate stenosis group[-61.75(-72.00,-45.38)](P＜0.001).Conclusion PFD,PFD/SNFD ratio are correlated with carotid plaque vulnerability.
