Ved minimale hodeskader (GCS 15 uten tilleggsrisiko) er det ikke indikasjon for CT.
Ved lette hodeskader med lav risiko (GCS 14 eller GCS 15 og mistenkt/bekreftet bevissthetstap og/eller gjentatte brekninger) kan normal S100B-blodprøve tatt < 6 timer etter skaden erstatte CT.
Ved lette hodeskader med middels risiko (GCS 14-15 og alder ≥ 65 år og platehemmende medisiner) er CT indisert, men kan erstattes av innleggelse for observasjon i 12 timer.
Ved høy risiko (posttraumatisk epilepsianfall, fokale nevrologiske utfall, tegn til skallebrudd, shuntbehandlet hydrocephalus eller koagulasjonsforstyrrelse/antikoagulasjonsbehandling) eller moderate hodeskader (GCS 9-13) skal det tas CT.
