Gliomas are the most common primary brain tumour, and in their most aggressive form, glioblastoma multiforme, are associated with a mean survival of 9-12 months. Despite maximal therapy, nearly all gliomas eventually recur. The majority of this recurrence is at the limits of previous resection / radiotherapy margins. We have combined 1H spectroscopy metabolite maps and DTI structural metrics of 30 histologically confirmed glioma patients to increase our understanding of the tissue changes that occur within the tumour and at the tumour-brain interface. We identify metabolite correlations with DTI metrics as a surrogate marker for tumour infiltration.
