My group uses advanced multimodal MR and PET imaging to understand the heterogeneity of gliomas (high and low grade) in individual patients. We know that gliomas are among the most heterogeneous tumours but still do not have a method of detecting this heterogeneity. Tissue markers cannot impact surgically based therapies. Imaging provides a non-invasive method of assessing tumour pathology.

My work focuses on two areas:

1. Intertumoural heterogeneity (i.e. differences between individuals). Especially heterogeneity of tumour invasion. Post-mortem studies show there is variation in tumour invasion with 20-25% of GBMs extend <1cm from the edge of the tumour mass, with another 20% extending >3 centimetres.

2. Intratumoural heterogeneity (i.e. differences within a tumour in an individual patient). Our work studies variation of response to chemotherapy/radiotherapy and drug uptake. We are developing [3-N-11C-methyl]-temozolomide a PET tracer to correlate response with drug uptake.

Diffusion tensor imaging can identify tumour invasion of normal brain in regions that appear normal on conventional imaging. Follow up imaging shows these abnormalities can predict the pattern of progression.
