In this work, we developed a post processing framework to generate multi-contrast images from a single three dimensional MR scan of multi-echo gradient echo sequence, which can alleviate the registration problem and further improve the scan efficiency with a total scan time of 3min22sec for carotid atherosclerosis imaging. The initial experiments has demonstrated its feasibility for vessel wall delineation and its potential for plaque component characterization.
