NCT ID NCT07285993
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares a new type of PET scan (FAPI) to the standard PET scan (FDG) in 15 people with metastatic invasive lobular breast cancer. The goal is to see if the new scan finds more cancer spots. Each participant will get both scans within a few weeks, and doctors will compare the results.
