Excerpt
Recent medical research has focused on the risks associated with increased radiation exposure among patients. Medical radiation exposure has increased 6-fold over the last 30 years.[
1] For example, currently in the US, approximately 250 million diagnostic x-rays are performed each year.[
2] Diagnostic computed tomography (CT) studies contribute even more to exposure. Since 1980, CT scans have increased from 3 million per year to 80 million per year.[
1] Consequently, radiation exposure for the average American has doubled since 1980.[
1] This revolution in medical imaging, while potentially lifesaving in achieving diagnosis, confers significant risk, primarily in the form of radiation-induced malignancy. Recent commentaries in
JAMA have cited several studies demonstrating the increased risk of primary malignancy among patients exposed to medical radiation.[
