New Raman probe detects brain cancer cells with more precision

A team lead by Frédéric Leblond, Professor at Polytechnique Montréal, and Kevin Petrecca, Chief neurosurgeon at the McGill University Health Centre, with collaborators at the Montreal Neurological Institute, McGill University and the MUHC has developped a new probe that can detect cancer cells in the brain with a precision higher than the existing technology.
The probe, which works by Raman spectroscopy, can detect cancer cells that are not detectable by Magnetic Resonance Imaging (MRI).
Using the Raman probe, surgeons could, in real time, detect with much more precision cancer cells located up to one centimeter away from tumours detected by MRI in patients suffering from very invasive forms of the disease.
This important breakthrough shows the power of light-based technologies for neuroscience applications.
Drs. Leblond and Petrecca were named Personnalités de la semaine – La Presse Radio-Canada this week, and was covered in many media outlets, including Radio-Canada, CTV and Scientific American.
