A new model-based reconstruction method is presented for accelerating 3D ultra-short echo time (UTE) parametric mapping. The proposed method enables accurate parameter mapping with significantly reduced data acquisition times. It should prove useful for 3D UTE relaxometry and various related applications (e.g., labeled cell tracking).
