Introduction: Minimizing radiation exposure for patients and staff in endoscopy- a joint ASGE/IAEA/WGO guideline

Ionizing radiation is used in medicine for both diagnosis and therapy. Most gastroenterologists are familiar with the use of radiographic methods for diagnosing gastrointestinal tract abnormalities, evaluating solid organs in the abdomen, and for assistance in placing therapeutic devices. It is essential to establish the appropriate indication for the use of radiation in all circumstances, in order to avoid unnecessary exposure of patients and staff to potentially harmful radiation. Therapeutic uses for radiation are beyond the scope of this guideline.
