TL;DR: To develop and assess a technique for self‐gated fetal cardiac cine magnetic resonance imaging (MRI) using tiny golden angle radial sampling combined with iGRASP (iterative Golden‐angle RAdial Sparse Parallel) for accelerated acquisition based on parallel imaging and compressed sensing.

TL;DR: 4D-flow with the Aera prototype sequence with a clinically acceptable acquisition time (<10 min) showed acceptable bias in healthy controls to be considered for clinical use.

TL;DR: This work develops an automated procedure to design single‐shot trajectories that create a local resolution improvement in a region of interest based on the design of optimized local k‐space trajectories and can be applied to arbitrary hardware configurations that employ any number of linear and nonlinear encoding fields.

TL;DR: A new performance measure of a matrix coil is presented from the perspective of efficient, local, non-linear encoding without explicitly considering target encoding fields to profit from using a single performance parameter that takes the local encoding performance of the coil into account in relation to the dissipated power.

TL;DR: PatLoc (Parallel Imaging Technique using Localized Gradients) accelerates imaging and introduces a resolution variation across the field‐of‐view and the source of these artifacts is analyzed and a reliable correction strategy is derived.
