Multi-contrast imaging is needed for comprehensive characterization of atherosclerosis, which often involves a series of separate scans. But the mis-registration between scans due to motion and the long scan time limits its application. So acquisition of multi-contrast images in one scan is preferable. In this study, we developed an inversion recovery prepared 3D golden angle radial sampling sequence enabling flexible posteriori selection of TI time and frame duration for arbitrary-contrast reconstruction. The proposed method may be a one-stop solution for 3D large coverage plaque imaging by providing inherently co-registered multi-contrast images in a single scan within short scan time.
