Proton magnetic resonance spectra representation acquired at magnetic field strength of 7 Tesla. The main individual metabolite peaks are labeled, with the x axis representing chemical shift in parts per million (ppm) and y axis indicating amplitude or concentration of the chemical. mTBI = mild traumatic brain injury; rmTBI = repeated mild traumatic brain injury; NAA = N-acetylaspartate.
