Magnetic resonance fingerprinting (MRF) is a promising method for simultaneous multi-parameter quantification. However, spatial coverage is limited in the original method due to the rapid image readout and the balanced sequence design. The aim of this study is to enable time-efficient volumetric coverage in Cartesian MRF-EPI for whole-brain quantification in clinically acceptable scan times. A slice-interleaved acquisition is shown to offer quantification precision comparable to single-slice measurements in a fraction of the measurement time. By combining this with simultaneous multi-slice imaging, whole-brain coverage with 40 slices was achieved in one minute, resulting in high quality T1 and T2* maps.
