There has been a rapid increase in the population dose from medical radiation within the last 20 years, particularly due to the increase in CT usage. Currently, about 65 million adult and 5 million pediatric CT exams are being performed in the US each year. CT-related x-ray doses are small, but very much larger than for most conventional radiological examinations. CT-related x-ray doses are large enough that there is statistically-significant epidemiological evidence of a small increase in…

Exposure of the Swiss population to computed tomography
Investigating the use of computed tomography in Switzerland, following the evolution of CT frequency and dose data over a decade and comparing it to data reported in other countries is comparable to those reported in a number of countries in Europe and America with similar health level.
Evaluation of an initiative to reduce radiation exposure from CT to children in a non-pediatric-focused facility
It is concluded that a non-pediatric-focused facility can achieve dramatic reduction in CT radiation exposure to children; however, this is most effectively achieved through a dedicated, multidisciplinary process led by pediatric radiologists.
Method of Reducing the Radiation Dose to the Paediatric Age Groups in Computed Tomography
These methods can be effective in reducing radiation dose while preserving diagnostic image quality in pediatric head CT examinations.
Radiation dose estimation in computed tomography examinations using NRPB-SR250 software in aretrospective analysis of a patient population.
The NRPB-SR250 software proved to be a robust tool for the assessment of organ doses and the effective radiation dose from CT, while challenges were encountered in finding the precise imaging data in retrospective protocols.
Radiation Safety in Patients
This chapter addresses questions and gives insight in the risk of ionizing radiation in molecular imaging techniques and how the protocols on the hybrid systems be optimized so that the patient gets the optimal imaging with a dose as low as reasonably achievable.
The Size-Specific Dose Estimate of Paediatric Head Ct Examinations for Various Protocols.
It was found that the implementation of the 11.1, 1.1 and 1.2 protocols were far lower than the axial and helical routine head protocols and it is essential for education to the medical personnel involved to implement the protocol of paediatric head CT to avoid an excessive dose of paediatrics in the head CT examination.
Optimizing radiation dose by varying age at pediatric temporal bone CT
Optimization of the tube current–time product allows a radiation reduction without a loss in image quality in pediatric patients undergoing temporal bone CT studies.
Correlation between age and head diameters in the paediatric patients during CT examination of the head
The aim of this study was to establish the relationships between the age and head patient size (Deff and the Dw) as the basis for calculating the size-specific dose estimate (SSDE) for paediatric head CT examination.
The Formulation of a Comprehensive Strategy for Computed Tomography Radiation Dose Optimization in Ontario
It is recommended that at least one specific approach be adopted by Ontario’s new CT dose management regulations, which are diagnostic reference levels, compliance monitoring, peer-review process and radiation protection committee.
Effect of CT Localizer Radiographs on Radiation Dose Associated With Automatic Tube Current Modulation: A Multivendor Study.
Localizer radiograph shows a significant influence on the radiation exposure but with different outcomes depending on the manufacturer of the CT scanner, Radiologists and radiographers should have a thorough understanding of these differences to assure patients the best examination.


Cancer risks from diagnostic radiology.
Concerns arise when CT examinations are used without a proven clinical rationale, when alternative modalities could be used with equal efficacy, or when CT scans are repeated unnecessarily.
The preliminary estimates of the NCRP Scientific Committee 6-2 medical subgroup are that, in 2006, the per capita dose from medical exposure (not including dental or radiotherapy) had increased almost 600% and the collective dose had increased over 700% to about 900,000 person-Sv.
CT dose reduction and dose management tools: overview of available options.
Modulation of the x-ray tube current during scanning is one effective method of managing the dose, but the tube current must be appropriately adapted to patient size for diagnostic image quality to be achieved.
Helical CT of the body: are settings adjusted for pediatric patients?
Pediatric helical CT parameters are not adjusted on the basis of the examination type or the age of the child, and results suggest that pediatric patients may be exposed to an unnecessarily high radiation dose during body CT.
Computed tomography--an increasing source of radiation exposure.
The facts are summarized about CT scans, which involve much higher doses of radiation than plain films, and the implications for public health are summarized.
Informing parents about CT radiation exposure in children: it's OK to tell them.
A brief informational handout can improve parental understanding of the potential increased risk of cancer related to pediatric CT without causing parents to refuse studies recommended by the referring physician.

The difficulties involved in quantifying the risks of low-dose radiation are reviewed, a linear extrapolation of cancer risks from intermediate to very low doses currently appears to be the most appropriate methodology, and a linearity assumption is not necessarily the most conservative approach.
Selective imaging strategies for the diagnosis of appendicitis in children.
Clinical outcomes and the number of imaging studies performed were modeled under current practice and under each guideline to increase diagnostic accuracy and reduce unnecessary testing for children with suspected appendicitis.
Solid Cancer Incidence in Atomic Bomb Survivors: 1958–1998
There was emerging evidence from the present data that exposure as a child may increase risks of cancer of the body of the uterus, and further evidence that radiation-associated increases in cancer rates persist throughout life regardless of age at exposure.
