A prospective evaluation of the value of repeat cranial computed tomography in patients with minimal head injury and an intracranial bleed.

Background: Patients with minimal head injury (MHI) and intracranial bleed (ICB) detected on cranial computed tomography (CT) scan routinely undergo a repeat cranial CT within 24 hours after injury to assess for progression of intracranial injuries. While this is clearly beneficial in patients with a deteriorating neurologic status, it is of questionable value in patients with a normal neurologic examination. The goal of this study was to prospectively assess the value of a repeat cranial CT in patients with a MHI and an ICB who have a normal neurologic examination.
