The symptoms of the brain tumour depend on the nature of the tumour, its location in the brain, its size and its rate of development.
Diagnosis of Brain Tumours
When a tumour is suspected, brain MRI is essential to visualize the affected brain region, the size of the lesion, and the nature of the tumour.
However, the definitive diagnosis is based on the removal of a tumour fragment, either by direct removal of the brain tumour, i.e. more or less complete removal of the tumour if its nature and characteristics assessed by MRI allow it, or by a simple biopsy in other cases.
At Paris Brain Institute
Researchers from Dr. Marc SANSON’s team and Dr. Emmanuelle HUILLARD, in collaboration with the CIM imaging platform, CENIR, have developed a new, non-invasive way of characterizing the properties of a particular type of tumour using magnetic resonance spectroscopy. This technology allows an MRI to quantify the activity of brain cells by identifying molecules associated with their metabolism.
In particular, work on this subject has made it possible to characterize the IDH mutation in patient tumours without the need for biopsy, which would have been essential for molecular analysis and mutation research.
