Answer :

Final answer:

Radioactive isotopes are used in PET scans to visualize body functions through radioactive emissions.


Explanation:

Radioactive isotopes are used in PET scans (positron emission tomography). PET scans utilize positron-emitting radioisotopes to create detailed images of the body's functions.

These isotopes are injected into the patient, and a PET scanner detects the gamma radiation emitted to generate images revealing organ activities.
