Videofluoroscopy and swallowing studies for neurologic disease: a primer.
Many patients with neurologic impairment due to stroke, multiple sclerosis, trauma, bulbar palsy, and other disorders have difficulty swallowing. Videofluoroscopy can provide important information on patterns of impairment of the swallowing mechanism, allowing important changes in patient treatment. The detailed videofluoroscopic evaluation required to provide this information is now seldom taught and is practiced by relatively few radiologists. The aim of this article is to (a) describe the indications for videofluoroscopic swallowing studies in the evaluation of patients with neurologic conditions affecting swallowing, (b) describe the techniques for evaluating the swallow mechanism with videofluoroscopy in a standardized manner, and (c) use cine videofluoroscopy to illustrate the range of abnormalities that can be demonstrated for some of these conditions and discuss the effect of patient treatment.
