Low-distortion Spine DWI with Ultra-high Shot and Navigator-free Reconstruction
Motivation: State-of-the-art low-rank methods recover multi-shot DWI with 2D structured matrix completion, but are hindered by long computation time (tens of minutes per image) and unsatisfactory ultra-high shot reconstruction (no more than 8-shot). Goal(s): Fast and reliable ultra-high (above 8-shot) DWI reconstruction. Approach: ODLRS: A 1D low-rank Hankel reconstruction method with self-adaptive subspace. Results: ODLRS is a novel 1D low-rank framework for multi-shot DWI reconstruction. Compared to conventional low-rank methods, ODLRS achieves 109 times accelerated reconstruction, and low-distortion spine DWI with 12 shots.SImpact: This work achieves fast (109 times acceleration) and reliable ultra-high (10 and 12 shots) DWI reconstruction, reducing the deformation of conventional spinal cord DWI significantly.
