Does head CT scan benefit patients presenting with syncope or dizziness to the emergency department?
Does head CT scan benefit patients presenting with syncope or dizziness to the emergency department?
Head CT scans in the ED for syncope or dizziness should be reserved for patients who are older, have focal neurologic deficits, or have recent head trauma.
May support selective head CT for ED syncope or dizziness; hypothesis-generating and requires prospective validation.
Our results suggest that most patients presenting with syncope or dizziness to the emergency department may not benefit from head CT unless they are older, have a focal neurologic deficit, or have a history of recent head trauma.
