1. The patient receives a radioactive material called an isotope in one of several ways:
   • Injection or IV
   • Capsules
   • Liquid
   • Special tubing
   • Inhalation

2. The isotope travels to target organs and tissues. Different isotopes are matched with different compounds that go to specific organs and tissues.

3. The isotope gives off gamma rays. A form of radiation that can be seen only with special equipment.

4. Special equipment provides images and readings of target organs and tissues. This equipment does not give off any radiation.

5. The images and readings are studied by a radiologist and the patient's healthcare provider.

Will a nuclear medicine scan make me radioactive?

No. The isotopes used:
• Are given in tiny amounts
• Lose their radioactivity very quickly (usually within hours)
• Pass out of the body quickly, usually within 24 hours

Do nuclear scans hurt?
Other than the minor discomfort of a needle stick, nuclear medicine scans are painless.

Who should not get nuclear scans?
They are generally not recommended for women who are pregnant or breastfeeding, but nearly everyone else can have these scans.
