Key result
Paediatric CT DRLs vary by clinical indication, falling below European and African standards for head trauma.
Why the study?
Diagnostic reference levels based on clinical indications for paediatric CT examinations were not established at the Mohammed VI University Hospital Centre in Marrakech.
Population
1730 paediatric CT examinations across three age groups (1–5, 5–10, 10–15 years)
Comparison
Diagnostic reference levels based on clinical indications vs published international standards from Europe and Africa
Design
Retrospective observational study at a single centre
Loading...
Provides institution-specific pediatric CT DRLs by indication and age; leaves open validation and dose-optimization impact beyond this center.
Observational (n=1,730)

p-value: p=<0.01
The study establishes clinical indication-based diagnostic reference levels for pediatric CTs in a Moroccan hospital, finding them generally higher than European but lower than African standards.
A 2025 study conducted an observational in Paediatric computed tomography (n=1,730). Computed tomography (CT) examinations was evaluated on Diagnostic reference levels (CTDI vol and DLP) based on clinical indications (p=<0.01). Diagnostic reference levels for paediatric CT varied significantly between clinical indications for CTDI vol (p<0.01), with head trauma DRLs lower than European and African standards.
