Overview of CT technologies for children

Pediatr Radiol. 2014 Oct:44 Suppl 3:422-6. doi: 10.1007/s00247-014-3043-8. Epub 2014 Oct 11.


Many technical advances in CT have reduced radiation exposure in children and adults. These advances in technology should be used in conjunction with CT techniques such as appropriate patient preparation and intravenous contrast media administration to maximize dose management and image quality. This article summarizes current dose reduction technologies for pediatric CT, noting ranges of dose reduction as well as potential limitations. Discussion includes some of the elusive aspects of assessing image quality and the need for developing personalized CT.
