Increasing the spatial resolution of MR Fingerprinting can result in longer acquisition times due to the need to sample a larger extent of k-space. In this work, a novel data sampling scheme consisting of interleaved high- and low-resolution spiral trajectories is introduced to achieve high-resolution maps during a shortened acquisition time, which could have advantages for sequences that require a breath-hold.
