In this study, a MSDE prepared spoiled gradient (SPGR) sequence was proposed to acquire black blood cine images of common carotid arteries (CCA) and investigate its dynamics quantitatively. Parameters related to dynamics of CCAs, including lumen areas, wall areas and distension were calculated and analyzed. Comparisons between black blood images and bright blood images were made. Based on this method, artery lumen dynamics and wall dynamics can be evaluated quantitatively, both of which may be valuable for investigating biomechanical and functional properties of the vasculature, monitoring vessel stiffness changes, and diagnosing related cardiovascular diseases.
