CT examinations constitute a major source of medical radiation exposure in the United States . The number of CT examinations performed in the United States increased from 3 million to 80 million between 1980 and 2010 . The growth of radiologic imaging has outpaced other components of health care spending. Appropriate utilization of imaging is important not only to prevent unnecessary cost, but also to ensure patient safety 3, 4. Incorrectly or inappropriately ordered radiologic examinations may result in an increased radiation dose, unnecessary exposure to intravenous contrast administration, or an inferior examination that would have benefited from contrast administration when none was requested. The patient may experience a delay or cancellation at the time of his or her radiology appointment to clarify or correct an inappropriately requested examination or may need to return for further imaging.
