3D-CT Evaluation of Swallowing: Metrics of the Swallowing Response Using Swallowing CT

Dysphagia. 2022 Apr;37(2):237-249. doi: 10.1007/s00455-021-10288-2. Epub 2021 Apr 5.

Abstract

Videofluoroscopy and videoendoscopy dramatically changed the evaluation and management of swallowing disorders. Later advancements in techniques for the instrumental evaluation of swallowing were limited by technique and positioning. The advent of 320-row area detector CT solved previous challenges and allowed for the study of swallowing physiology and dysphagia in greater detail. In this summary, we describe the history and evolution of CT technology and describe research and clinical applications for the evaluation of swallowing physiology and pathophysiology.
