The Infant Scalp Score (ISS) is a clinical tool used to assess the risk of traumatic brain injury in infants presenting with scalp hematomas following head trauma. The score supports decision-making regarding the need for neuroimaging and aims to reduce unnecessary head CT scans. It has been evaluated in the context of improving risk assessment in pediatric head trauma.
