Spiral readout was used to accelerate the standard T1-weighted 3D head scan based on MPRAGE at 3 Tesla without any compromise on images quality. The encoding model used by the reconstruction included the static magnetic field map as well as the k-space trajectory and a dynamic field correction provided by a field camera. The study demonstrates the utility of state-of-the-art spiral scanning for routine MRI applications.
