Interventional procedures are becoming routine around the world, owing to their successful clinical outcome and improved patient safety. However, they can be difficult and demanding, since the physician must simultaneously consider many technical and clinical aspects. Although the patient’s condition carries a more substantial risk compared with radiation dose, the increasing number of reports of adult radiation injuries has highlighted various issues of patient radiation safety.
