Evaluating Positron Emission Mammography Imaging of Suspicious Breast Abnormalities

Official Title

A Pilot Study to Evaluate Low-Dose Positron Emission Mammography Imaging in Visualization and Characterization of Suspicious Breast Abnormalities


The goal of this pilot project is to test the new Radialis Positron Emission Mammography (R-PEM) system in breast cancer patients that has a higher sensitivity with lower radiation doses than conventional PET/CT. The plan for the pilot study is to image patients who are already scheduled for diagnostic imaging for breast cancer after a positive core biopsy. Participants will be injected with 5mCi of F-18 FDG and patient will wait for a couple of hours for uptake of FDG. After this time, the first R-PEM scan will occur. Additional optional R-PEM scans can be performed 4 hours after injection and 7 hours after injection with reductions in radiation emission. Additionally, R-PEM images will be compared to standard-of-care breast MRI and digital breast tomosynthesis to study extension of disease and screening of contralateral breast.
