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.
