In this study, we compared morphological measurements and identification of plaque components in carotid artery between 2D and 3D multi-contrast vessel wall MRI techniques. 3D multi-contrast vessel wall imaging, with 0.8mm isotropic resolution and 15min total scan time, showed good inter-reader reproducibility and provided comparable morphological information as 2D multi-contrast imaging, and more importantly, has its potential to improve visualization of plaque components.
