A twisted projection imaging sequence is presented. The properties of the k-space trajectory are used to reduce scan time in 3D imaging. The sequence was implemented as a spoiled gradient recalled echo (SPGR) sequence and as a fully balandec steady-state free precession (bSSFP) sequence. The different contrast behaviors of these sequences are used for fast 3D mapping of T₁ and T₂ with a variable flip angle approach.
