Summary

This completed study looked at 44 people with a type of brain tumor called glioma. Researchers used a special MRI scan to see if the swollen brain tissue around the tumor still had working connections. They then took small tissue samples during surgery to check if the scan results matched what was seen under a microscope. The goal was to better understand this swollen tissue, not to test a new treatment.
