The use of spiral trajectories is an efficient way to cover a desired k‐space partition in magnetic resonance imaging (MRI). Compared to conventional Cartesian k‐space sampling, it allows faster acquisitions and results in a slight reduction of the high gradient demand in fast dynamic scans, such as...
