First seen Jan 26, 2026 · Last updated Apr 29, 2026 · Updated 16 times

Summary

This study tested whether a dye called indocyanine green can make brain and spinal cord tumors glow during surgery, helping surgeons see and remove them more completely. About 363 adults with brain tumors received the dye before surgery, and special cameras were used to detect the glow. The goal was to improve how much tumor is removed, which may lower the chance of the tumor coming back.
