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
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
