For most people, SPECT scans are safe. If you receive an injection or infusion of radioactive tracer, you may experience:

  • Bleeding, pain or swelling where the needle was inserted in your arm
  • Rarely, an allergic reaction to the radioactive tracer

Your health care team uses the lowest amount of radiation possible in order to perform the scan. Talk to your doctor if you're concerned about your exposure to radiation during a SPECT scan.

Be sure to tell your doctor if you’re pregnant or breast-feeding. The radioactive tracer used in a SPECT scan may affect a developing fetus or nursing baby.
