200 infants (<2 years old) will be enrolled into the study. Clinical data will be gathered from the emergency room file, and in case of admission from the discharge letter and the clinical file. Based on the current protocols of treatment and diagnosis of children with head injury, CT will be performed according to the current axisting protocols. No intervention, imaging, or treatment will be administered different from the current protocol used in the hospital, according to the existing guidelines. Both TINS and Children's Glasgow Coma Scale (CCS) score was applied, based on the clinical data obtained from the files. If imaging is peformed data will be recoreded. As all children with head trauma are invited routinely to follow-up clinic within the 1st year after injury, this data will be recoreded as well.
