A low threshold for neuroimaging (CT or MRI) should be used for infants who present with bruising, vomiting without fever or diarrhea, fussiness or lethargy, or transient loss of consciousness (apparent life-threatening event [ALTE] and brief, resolved, unexplained event [BRUE]), especially those with increased head circumference or anemia.
