MRS thermometry has been used to characterise two different childhood brain tumour types at low echo time. The PRF measure is dependent on temperature, ionic concentration and chemical exchange. These factors are useful for diagnosis and prognosis of tumours, as they relate to the micro-environment of the tumour. In this study we investigate long echo MRS thermometry to improve the understanding these factors on the PRF measure.
