3D magnetic resonance fingerprinting (MRF) techniques have been developed to efficiently acquire 3D volumes of quantitative parameters. Most techniques are based on applications of 2D trajectories rotated or stacked in 3D k-space. By acquiring data across all of 3D k-space each TR, we believe that efficient imaging and quantification can be obtained. In this study, seiffert spirals are used to acquire 3D k-space in an MRF acquisition of an isotropic 3D volume for the quantification of T1 and T2 relaxation times. High resolution T1 and T2 maps of a human brain were acquired in less than 3 minutes.
