This study presents a new approach which minimizes spiral image blurring on a whole-body 7T scanner. A combined use of multi-shot spirals and ultra-short echo time (UTE) acquisitions was implemented in this approach and high-resolution (0.22mm) brain images of healthy volunteers were obtained. These T1-weighted FID-based images clearly show the effectiveness of the proposed approach.
