In the evaluation of simple syncope and a normal neurologic examination don’t obtain brain imaging studies (CT or MRI).
|Rationale and Comments:||In patients with witnessed syncope, but with no suggestion of seizure and no report of other neurologic symptoms or signs, the likelihood of a central nervous system cause of the event is extremely low and patient outcomes are not improved with brain imaging studies.|
