Nearly half of all emergency department (ED) visits in the United States result in some type of imaging study, a large number of which are performed for neurological complaints.

This chapter seeks to provide guidance in imaging modality selection and to discuss imaging findings in common clinical presentations to the ED. When pertinent, alternative and recommended follow-up studies are also discussed
