Luminal stenosis level, IPH, calcification and lipid rich necrotic core are biomarkers for vulnerable plaques. Currently available 2D multi-contrast black-blood MRA schemes suffer from small FOV, low SNR and misregistration between sequences. In this study, we develop a new sequence which combines the advantages of 3D-MERGE and SNAP into a single 3D sequence that provides large-coverage plaque imaging to visualize MRA, lipid core, calcification and IPH simultaneously.
