Multinuclear MR provides important information concerning cell integrity or energy metabolism. PET uses radioactive tracers to gain valuable insights into physiological and metabolic processes with both a high level of sensitivity and specificity. Here, we explored the combination of sequential multinuclear MR and PET in a rat brain tumour model. This allows in vivo multinuclear MR-PET experiments to be carried out without compromising the performance of either multinuclear MR or PET. In vivo multinuclear MR and PET images and spectra from rats with/without brain tumours confirmed the potential use of the different X-nuclei derived metabolic information.
