Ultrasound can be a useful tool in the assessment of pediatric trauma, especially in the well, haemodynamically stable patient. 

Correlation between CT findings and Ultrasound (in the hands of a professional) can be high. In some cases, a good quality ultrasound and low clinical concern can obviate the need for CT completely. However, CT is often required to confirm grade of injury and to definitively rule out associated injuries.

CT in children can be confined to the area of interest (in this case, just the upper abdomen) and should be protocolled as a dual bolus technique.
