Paediatric computed tomography diagnostic reference levels in Africa: A systematic review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 139-147, March 2025.
Improvements in computed tomography (CT) technology have increased its applications in medical imaging. Variations in the paediatric DRLs indicate that harmonisation and standardisation of paediatric CT protocols are essential for the optimisation of paediatric doses. Abstract Introduction Improvements in computed tomography (CT) technology in terms of
