What is nuclear medicine and how does it work?

Nuclear medicine is a medical specialty that uses radioactive materials for diagnosis and treatment. It involves administering small amounts of radioactive substances to patients, which can be detected by imaging devices.

What are some common procedures in nuclear medicine?

Common procedures include PET scans, SPECT scans, and radioiodine therapy for thyroid conditions. These help in diagnosing various diseases.

Are there any risks associated with nuclear medicine?

Yes, there are some risks, such as exposure to radiation, but the doses used are generally low and the benefits often outweigh the risks.

How is nuclear medicine different from traditional imaging techniques?

Unlike traditional imaging, which captures structural images, nuclear medicine provides functional information about organs and tissues, allowing for a more comprehensive assessment.

Can you explain how a PET scan works?

A PET scan involves injecting a small amount of radioactive glucose into the body. Cancer cells absorb more glucose, allowing the scan to highlight areas of abnormal activity.
