Mouse brain structural and metabolic stability were determined by T1 and T2 mapping and DTI at 0.7 and 0.9 s of 4 kW FBMI and by quantitative single voxel PRESS, respectively. Measures were taken in-vivo before and repetitively, at 1.17 hour intervals, after FBMI. Analysis continued for a total duration of 16 hours at room temperature. The longer FBMI duration was best for maintaining metabolite levels in the mouse brain; whereas T1, T2, and DTI metrics were best maintained by shorter duration FBMI.
