Summary
Paediatric computed tomography (CT) use decreased significantly over a decade, while overall CT use increased. Appropriateness of paediatric CT scans improved, but further interventions are needed to optimize imaging referrals.
Area of Science:
- Radiology
- Medical Imaging
- Pediatric Imaging
Background:
- Paediatric computed tomography (CT) utilization has evolved over the past decade.
- Assessing the appropriateness of these examinations is crucial for optimizing patient care and resource allocation.
Purpose of the Study:
- To analyze trends in paediatric CT utilization over ten years.
- To evaluate the appropriateness of paediatric CT examinations at a tertiary teaching hospital.
Main Methods:
- Prospective data collection of paediatric CTs in 2022, compared with 2017 and 2012 data.
- Evaluation of CT justification against medical imaging referral guidelines.
- Calculation of appropriateness rates for paediatric CT examinations.
Main Results:
- Paediatric CT use declined by 39.4%, while overall CT use rose by 27.6%.
- The proportion of paediatric CTs within overall CTs decreased from 2.5% to 1.1% (P < .0001).
- Overall CT appropriateness improved from 73.1% (2017) to 79.0% (2022) (P = .0049), with highest rates for angiography and chest, and lowest for head and neck.
Conclusions:
- Improvements in CT justification can be achieved through educational interventions, enhanced MRI accessibility, and pre-examination appropriateness reviews.
- Targeted interventions are necessary for effective implementation of referral guidelines, particularly for head and cervical spine trauma in paediatric patients.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
