Optimized <scp>MR</scp> pulse sequence for high‐resolution brain <scp>3D</scp>‐T1ρ mapping with weighted spin‐lock acquisitions
Compared with the 20-min MAPSS sequence for brain T1ρ mapping, the proposed learned high-resolution 3D pulse sequence simultaneously achieved a 2.3-fold improvement in effective (3.2-fold nominal) spatial resolution, a 1.1-fold improvement in SNR, and a 2.5-fold reduction in scan time.
