Trial Parameters
Brief Summary
Low grade gliomas (LGGs) are malignant, infiltrative and incurable brain tumours that typically present in the younger population. This project proposes to use non-contrast metabolic "Saturation Transfer" (ST)-MRI to evaluate LGG tumour progression and aims to predict early changes in LGG. Early identification of LGG patients whose tumours will progress will permit early interventions. ST-MRI does not involve any intravenous injection of contrast and which acquires metabolic information not seen by standard MRI.
