Using Complementary Poisson Disk (CPD) sampling, we accelerate multi-echo gradient recalled echo acquisitions (ME GRE) by efficiently undersampling k-space in such a way that lends itself to practically realizable sampling trajectories. We reconstruct $$$T_{2}^{*}$$$ maps from these undersampled acquisitions and validate against fully sampled data.
