Do not perform computed tomography (CT) or nuclear magnetic resonance imaging (MRI) of the brain to patients who have experienced transient loss of consciousness in the absence of other neurological symptoms and have normal neurological examination. Adapted from the American College of Physicians
In patients who have experienced a witnessed loss of consciousness, without the suspicion of seizure and in the absence of other neurological signs or symptoms, the probability that central nervous system damage is the cause is very low and imaging of the brain does not improve prognosis. Imaging of the brain may be indicated in selected cases in which head trauma caused by loss of consciousness is suspected.
