Safety precautions

Allergies
 
Allergic reactions to radiopharmaceuticals may occur but are extremely rare and are usually mild. When preparing for your appointment, please inform the technologist of medications you are currently taking or if you have any known allergies to intravenous contrast material, iodine or seafood.
 
Side effects
 
Some patients may experience slight pain and redness from the radioactive sugar injection called fluorodeoxyglucose, also known as FDG. However, these symptoms often resolve very quickly without any complications.
 
Pregnant or breastfeeding women
 
Women should inform their doctor or radiology technologist if they may be/are pregnant or breastfeeding. It is recommended that breastfeeding women pump breast milk before a scheduled PET scan appointment. Breastfeeding can safely resume approximately two hours after a PET has been completed, which is when the PET radiopharmaceuticals are no longer present in the body. For more information about pregnancy and breastfeeding related to nuclear medicine imaging, please refer to the Safety in nuclear medicine procedures section by RadiologyInfo.org.
