Complications of fluoroscopy are not common, but any medical procedure involves risk and potential complications. There is a small increase in the risk of cancer due to radiation exposure with fluoroscopy. Your care team follows strict standards for X-ray techniques and will use the smallest amount of radiation possible to produce the best images. Your doctor will generally not use fluoroscopy if you are pregnant because radiation can cause birth defects. It is important to tell your doctor and care team if there is any chance that you are pregnant. Allergic reactions to contrast materials are rare, but can occur. Fluoroscopy teams are well prepared to handle allergic reactions.
