We investigated the feasibility of simultaneous mapping of interslice blood flow, MTR asymmetry, and MTR, using a recently developed method, alternate ascending/descending directional navigation (ALADDIN). The cumulative MT effects in edge slices from simulations based on a modified two-pool MT model were in agreement with empirical results . Simultaneous mapping of blood flow, MTR asymmetry, and MTR in the whole brain was feasible with ALADDIN within a clinically reasonable time of &[le]~7 min. Our proposed method provides readily a full spectrum of MR measurements useful to characterize a wide range of brain pathological conditions and functional evaluation.
