Computed tomography (CT) has been proven to be able to accurately diagnose splenic injury. Many have published CT splenic injury grading scales to quantify the extent of injury. However, these scales have failed at predicting clinical outcomes and therefore cannot be used to accurately predict the need for intervention. We hypothesised that low interrater reliability is the reason why these scales have failed at predicting clinical outcomes. ⋯ The six studied CT splenic injury grading scales did not have a high enough interrater reliability to be adequate for clinical use. The poor interrater reliability is likely to contribute to the failure of the scales at predicting clinical outcomes. Further research to improve the interrater reliability is recommended.

The use of CT has rapidly increased since its introduction. Although an important medical tool for diagnosis and treatment, CT is recognised as being among the highest contributors to population radiation exposure. As the risks associated with exposure are higher for children than for adults, this study assessed the impact of paediatric CT in Australia by analysing imaging trends. ⋯ The significant growth in CT services is attributable to increased demand from the adult demographic. Conversely, increases in the imaging rate for paediatric patients have slowed overall. In fact, for some age groups the rate has fallen.
