About nuclear medicine

Nuclear Medicine is a branch of radiology (medical imaging including X-rays, CT scans, and MRI). It uses small amounts of radioactive materials (called radiopharmaceuticals) to diagnose or treat certain diseases or conditions.

There are many different types of radioactive materials used in nuclear medicine. Which one is used depends on the condition being treated or diagnosed. Most radioactive materials are injected into your body but some need to be swallowed or breathed in.

Nuclear medicine imaging helps with diagnosing and assessing medical conditions.
