Book excerpt: The new edition of the book Normal and Abnormal Swallowing, Second Edition, presents an updated practical approach to the role of imaging in the diagnosis and treatment of the patient with dysphagia. Centered around the "gold standard" imaging modality, i.e. videofluorography, the text also includes chapters on other modalities such as ultrasound, computed tomography and magnetic resonance imaging. The broad scope of the text makes it the definitive reference work for professionals already involved with patients with dysphagia as well as newcomers interested in learning more about the imaging approaches to these patients. This is a "must read" for professionals in specialities such as radiology, gastroenterology, otolaryngology, rehabilitation medicine and speech language pathology.
