Comparing risk estimates following diagnostic CT radiation exposures employing different methodological approaches.

The current study has two aims: the first is to quantify the difference between radiation risks estimated with the use of organ or effective doses, particularly when planning pediatric and adult computed tomography (CT) examinations. The second aim is to determine the method of calculating organ doses and cancer risk using dose-length product (DLP) for typical routine CT examinations. In both cases, the radiation-induced cancer risks from medical CT examinations were evaluated as a function of gender and age.

Methodology for estimating cancer risks of diagnostic medical exposure: with an example of the risks associated with computed tomography.

Because of fast growing medical radiation use, estimating possible late health effects of radiation, including potential cancer risk, is an issue of substantial interest. Since physicians make the decision to order or perform a radiological procedure, it is very important to provide them with objective information about possible radiation-associated risks. Methodology for estimating cancer risks based on recommendations of ICRP Publication 103 is presented in the paper.
