A HIDA scan carries only a few risks. They include:

  • Allergic reaction to medications containing radioactive tracers used for the scan
  • Bruising at the injection site
  • Radiation exposure, which is small

Tell your doctor if there's a chance you could be pregnant or if you're breast-feeding. In most cases, nuclear medicine tests, such as the HIDA scan, aren't performed in pregnant women because of potential harm to the fetus.
