Low field magnetic resonance systems have potential as powerful diagnostic tools at comparably low cost. However, the inherently lower signal requires the use of SNR-efficient pulse sequences and reconstruction schemes. In this work, we present initial results with a hybrid-state free precession sequence, used to quantify T1 and T2 in 12min with an isotropic resolution of 1mm3. Visually, these quantitative maps show low noise levels, which allows for compelling synthetic MP-RAGE contrast generation.
