In this study we introduce a new DANTE-prepared 3D FLASH T1 weighted (T1w) sequence (denoted 3D-DASH) that is able to generate 0.6 mm isotropic resolution carotid artery intra-plaque haemorrhage images with an imaging speed better than 2 sec/slice. Imaging efficiency comparisons were also made between the current best 3D black blood (BB) technique, MSDE prepared FLASH (3D-MERGE)and the new 3D-DASH technique.
