13C-MRSI SNR for mMR water phantom measurements. Plots show urea (blue symbols) and acetate (red symbols) SNR for 13C-MRSI scan numbers 17 to 40. For scan numbers 21–24 and 33–36, the PET gantry was switched off, as indicated by the yellow bar. The PET activity was high and low for scan numbers 17–28 (a) and scan numbers 29–40 (b), respectively
