=====3D FDP FSPGR===== Three-dimensional (3D) MR black-blood sequence flow-dephasing-prepared fast spoiled gradient recalled echo (FDP-FSPGR). The 3D FDP-FSPGR can be used for high-spatial-resolution demonstration and large coverage of the [[basilar artery]] wall and the ostia of the adjacent branch arteries. This sequence will make it possible to evaluate therapeutic effects in clinical studies ((Lou X, Ma N, Shen H, Shi K, Jiang W, Ma L. Noninvasive visualization of the basilar artery wall and branch ostia with high-resolution three-dimensional black-blood sequence at 3 tesla. J Magn Reson Imaging. 2014 Apr;39(4):911-6.
