X rays over your lifetime

The decision to have an x ray exam is a medical one, based on the likelihood of benefit from the exam and the potential risk from radiation. For low dose examinations, usually those that involve only films taken by a technologist, this is generally an easy decision. For higher dose exams such as computed tomography (CT) scans and those involving the use of contrast Materials (dyes) such as barium or iodine, the radiologist may want to consider your past history of exposure to x rays. If you have had frequent x ray exams and change healthcare providers, it is a good idea to keep a record of your x ray history for yourself. This can help your doctor make an informed decision. It is also very important to tell your doctor if you are pregnant before having an exam that involves the abdomen or pelvic region.
