The Clinical and Radiological Approach to Dysphagia
The intention of this chapter is to introduce a multi-disciplinary diagnostic work-up and, in particular, to present a practical and structured radiological approach. Swallowing disorders are common. U.S. statistics indicate that more than 5 % of the population has swallowing difficulties, and in hospitals up to 50% (Logemann 1995). The swallowing tract crosses many anatomic regions. Liquid and solid foods have to be transported properly from the oral cavity into the pharynx and through the esophagus into the stomach. Thus, a wide variety of diseases may affect deglutition, resulting in a multidisciplinary work-up of dysphagic patients. Videofluoroscopy (VF) of deglutition is the method of choice to investigate the whole swallowing tract in a ‘‘one-stop-shopping’’ fashion. VF can depict patho- logic findings of morphology and function as a basis to decide on a further specialized work-up.
