Summary

This study looks at 69 past brain scans using a special tracer called [18F]FET to see if it can more accurately tell the difference between a returning tumor and changes caused by previous treatment. Researchers will analyze both still and time-lapse images to find better ways to diagnose and classify brain tumors. The goal is to improve how doctors use this type of PET scan in everyday care.
