Abstract

Quantitative 23Na MRI provides useful information about brain tissue homeostasis. Most sequences use deterministic non-Cartesian 3D trajectories such as TPI. However, stochastic strategies such as SPARKLING could improve the coverage of k-space. This study evaluates the advantages of SPARKLING versus TPI. From in vivo datasets at 7T, we determined that undersampled SPARKLING acquisitions outperform TPI for (8 mm)3 resolution with a birdcage coil or for (4 mm)3 with a 32-channel coil. Through extrapolation of these results, we predict that at 11.7T/32-channel, 23Na MRI data could be acquired in 90s at (3 mm)3, which could be interesting for sodium fMRI imaging.
