18F-FES PET/MRI for tailoring treatment of luminal A and lobular breast cancer: a phase II trial evaluating the performance of FES PET/MRI in axillary staging

This study is looking at a new type of scan called FES PET/MRI for women with certain types of breast cancer. We want to see if it's better than standard ultrasound at finding cancer in the lymph nodes under the arm.
