Clinical Policy: Neuroimaging and Decisionmaking in Adult Mild Traumatic Brain Injury in the Acute Setting October 24, 2001 I. Is there a role for plain film radiographs in the assessment of acute MTBI in the ED? Recommendation B: Skull film radiographs are not recommended in the evaluation of MTBI.

Indeed, negative findings on skull films may mislead the clinician. II. Which patients with acute MTBI should have a noncontrast head CT scan in the ED? Recommendation A: A head CT scan is not indicated in those patients with MTBI who do not have headache, III. Can a patient with MTBI be safely discharged from the ED if a noncontrast head CT scan shows no evidence of acute injury?
