In this study we investigate the feasibility of a 3D turbo spin-echo imaging technique with variable flip angle combined with an undersampled Cartesian variable density trajectory (3D TSE-VDCASPR) for efficient whole-heart black-blood imaging. Data from five healthy subjects are acquired with the proposed 3D TSE-VDCASPR and the conventional 3D TSE with Cartesian GRAPPA. The proposed imaging 3D TSE-VDCASPR imaging technique allows for comparable black-blood imaging, with the advantage of reduce nominal scan time (4.6±1 vs 8.1±1.6 minutes ± seconds). Future work will investigate more advanced motion compensation and image reconstruction techniques in order to achieve predictable and fast scan time.
