Summary

This early-phase study aims to see if a special PET scan using 89Zr-trastuzumab can predict how well HER2-positive breast cancer patients will respond to targeted therapy. Ten newly diagnosed adults will receive the imaging agent and undergo PET/MRI scans. The goal is to improve treatment selection by identifying responders before therapy begins.
