Radiation exposure in gastroenterology

The most recent issue of the American Journal of Gastroenterology examines improving patient and staff protection during exposure to radiation in gastroenterology.

News image

Medical imaging involving the use of ionizing radiation has brought enormous benefits to society and patients.

In the past several decades, exposure to medical radiation has increased markedly, driven primarily by the use of computed tomography.

Ionizing radiation has been linked to carcinogenesis.

The use of medical radiation must always be justified
American Journal of Gastroenterology

Whether low-dose medical radiation exposure will result in the development of malignancy is uncertain.

Dr Eamonn Quigley and colleagues from Texas, USA reviewed the current evidence for such risk.

The team informed the gastroenterologist of dosages of radiation associated with commonly ordered procedures and diagnostic tests in clinical practice.

The use of medical radiation must always be justified, and must enable patients to be exposed at the lowest reasonable dose.

Dr Quigley's team comments, "Recommendations provided herein for minimizing radiation exposure are based on currently available evidence and Working Party expert consensus."
