WI surgeons use new tech to improve brain tumor removal

Green Bay, WI (WXOW) - Neurosurgeons in Wisconsin employ some new technology to try to better remove a complex brain tumor.

Under normal white light used while operating, neurosurgeons could only see portions of the tumor. But thanks to a new dye and filter system, they can see more.

The tumor shows up as pink while the normal tissue is blue under the special filter. That's because after patients drink the dye called Gleolan about four hours before surgery, the dye binds to a protein only present in Glioma tumors.

The dye fades after a few hours and reportedly has few side effects.
