Clinical Decision Rules for Pediatric Head Trauma Imaging

Quick fact

The PECARN rules for pediatric head trauma can identify children at extremely low risk of clinically important brain injury (less than 0.05% risk) and allow doctors to safely skip CT scans in many cases, sparing children from radiation.

Why this is interesting

Imagine you’re a parent in the ER with a child who fell and hit their head. The doctor must decide: CT scan or not? Would you want a scan to be safe, or avoid radiation to protect your child?
