Diagnostic reference levels for chest computed tomography in children as a function of patient size

Pediatric Radiology, 2022
Radiation exposures from computed tomography (CT) in children are inadequately studied. Diagnostic reference levels (DRLs) can help optimise radiation doses.

Establishment of CT diagnostic reference levels in Ireland [PDF]

The British Journal of Radiology, 2012
To propose Irish CT diagnostic reference levels (DRLs) by collecting radiation doses for the most commonly performed CT examinations.A pilot study investigated the most frequent CT examinations. 40 CT sites were then asked to complete a survey booklet to allow the recording of CT parameters for each of 9 CT examinations during a 12-week period.
