Revolutionary New Probe to Improve Intraop Brain Cancer Detection

Researchers at the Montreal Neurological Institute and Hospital and Polytechnique Montréal have developed a new spectroscopy probe to detect different types of brain tumors.

The revolutionary new technology allows neurosurgeons to locate brain neoplasms in real-time and could potentially become the new standard in brain surgery. Healthy brain tissue is difficult to differentiate visually from cancerous type, and patients who have these tumors removed often need to have follow up surgery again as not all of the cancer was taken out.


The device emits laser light onto the tissue and acquires a signal that can determine some characteristics of the molecular makeup within. The Raman probe can identify cancerous tissue 92% of the time, and the probes have been tested intraoperatively on patients with gliomas of grade 2, 3, and 4.

Clinical studies have been planned to take place at the Montreal Neurological Institute and Hospital on patients with recurrent and newly diagnosed glioblastoma.
