Inflammation of carotid artery perivascular adipose tissue (PVAT) is associated with atherosclerotic disease. This study investigated the association between carotid artery PVAT and atherosclerotic plaques using multi-contrast MR vessel wall imaging. The contrast-to-noise ratio (CNR) of PVAT was measured on TOF MRA images. We found that the CNR of carotid artery PVAT measured by TOF MRA is independently associated with carotid vulnerable plaque features, suggesting that the CNR of PVAT might be a potential indicator for vulnerable atherosclerotic plaques.
