An arthrogram is generally safe, but with any study, there are a few things to keep in mind: • Allergic reactions to the contrast dye are rare, but it is important to let your physician and our technologist know if you had any reactions to iodine or gadolinium in the past. • A small dose of radiation is used during the study, so if there is any chance you might be pregnant, please inform our technologist or your physician.  • If you have active arthritis or a joint infection, an arthrogram might not be suitable for you. It's important to discuss your medical history with your physician beforehand to ensure the study is safe for you.
