What you'll likely be quizzed about
- Nuclear radiation is used in medical imaging through techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT).
- These processes involve administering small amounts of radioactive isotopes to the patient, which emit gamma rays detectable by specialized cameras.
- The emitted radiation generates images that reveal functional processes within the body, allowing for early detection of diseases such as cancer and heart conditions.
