The overall duration of acquiring a Nyquist sampled 3D dataset can be significantly shortened by enhancing the efficiency of k-space sampling. This can be achieved by increasing the coverage of k-space for every trajectory interleave. The presented and adapted acquisition scheme using Seiffert Spirals can be a valuable tool for applications in which scan durations are strictly limited e.g. in the case of 3D ECG gated cardiovascular imaging. In this context we apply the Seiffert Spirals to isotropic whole heart imaging with overall scan times of 350 heart beats for a resolution of (1.25 mm)3.
