CTA neck criteria from Taming of the Sru Grand Rounds directly quoted below:
Guidelines for imaging: GCS<8, audible neck bruit, expanding neck hematoma, focal neurologic deficit (including TIAs, Horner’s syndrome, vertebrobasilar syndrome), arterial bleeding from nose, mouth, neck
OR consider adding on if high C spine fracture, cervical vertebral body or fracture through foramen transversarium, subluxation or ligamentous injury at any level, significant thoracic/cardiac blunt force trauma, LeFort II or III fractures, skull base fracture, diffuse axonal injury
CTA neck AND head (can miss top of carotids with just CTA neck)
CXR
