Spectrally selective 31P MRI can be of interest for the study of brain energetics for clinical research. Using a 3D SSFP sequence with non-Cartesian Twisted Projection Imaging sampling, we obtained whole-brain images of ATP and PCr in healthy volunteers at 7 Tesla with a higher normalized SNR than with CSI. Local concentration quantification was performed using the phantom replacement approach after accounting for the T1/T2-weighting and the transmission and reception profiles of our coil yielding consistent results.
