Nuclear Medicine
Nuclear medicine uses radioactive substances in diagnosis and therapy. Nuclear breast imaging (also called scintimammography) is a supplemental breast exam that may be used in some patients to investigate a breast abnormality after diagnostic mammography has been performed. Nuclear breast imaging uses small amounts of radioactive materials, or radiopharmaceuticals, to do diagnostic scans of the breast.
