Abstract
Objectives To benchmark and standardize regional practice for paediatric cranial CT procedures, in terms of radiation dose and acquisition parameters. Methods Paediatric cranial CT data were retrospectively collected during 1-year, in 3 hospitals of the same country. A dose tracking system was used to automatically gather information. Radiation dose (CTDI and DLP) were stratified by age and clinical indication. Scan length, amount of retakes and demographic data were acquired; appropriate use of child specific protocols was assessed. Results In total, 296 paediatric cranial CT procedures were collected. Although the median dose of each hospital was below the national and international diagnostic reference level (DRL) for all age categories, statistically significant ( p -value Conclusion Even though all hospitals complied with national and international DRLs, dose tracking and benchmarking showed that further dose optimization and standardization is possible by using age-stratified protocols for paediatric cranial CT. Moreover, having a dose tracking system revealed that adult protocols are still applied for paediatric CT, a practice that must be avoided.
