High-resolution MPRAGE has become a standard structural imaging sequence in clinical settings yet it is difficult to repeat the scan because of its relatively long acquisition time. Acceleration techniques allow the reduction of acquisition times although excessive acceleration can result in artifacts. We implemented a fast MPRAGE sequence using a spiral trajectory and demonstrated segmentation of acquired images. The spiral MPRAGE can acquire a whole-brain T1 volume in less than 25% of the acquisition time of the conventional MPRAGE while maintaining comparable contrast and segmentation results.
