New PET tracer could spot rare brain tumors without surgery

This study is testing a new radioactive tracer called 68Ga-MY6349 to see if it can help diagnose craniopharyngioma, a rare brain tumor, using PET/CT scans. The tracer targets a protein called Trop-2, which is often found on these tumors. Twenty participants with suspected or confirmed craniopharyngioma will receive one injection of the tracer and then undergo imaging. The goal is to see if the tracer can accurately detect the tumor and measure Trop-2 levels, potentially offering a non-invasive alternative to surgery for diagnosis.
