Imaging of patients with clinical dysphagia is performed for two main reasons. First, cinepharyngography is used to identify pharyngeal masses and/or document physiological swallowing abnormalities. This test includes efforts to differentiate intrinsic from extrinsic pharyngeal lesions and categorize the physiological type of swallowing disorder. The pharyngogram is a relatively sensitive physiological technique, but is often anatomically insensitive and physiologically nonspecific. Smaller pathological lesions elude detection by this technique and only gross anatomical localization of larger lesions is usually possible. Furthermore, demonstration of the precise neuroanatomical substrate of a physiological swallowing disorder requires other imaging techniques. Until the last 15 years, actual identification and delineation of pathological lesions accounting for dysphagia was difficult and relatively unusual.
