摘要：

Due to long scan times it was impossible to make dynamic swallowing imaging using computer tomography (CT) of the third or fourth generation. This study evaluates whether electron beam tomography with scan times of 100 ms enables a more detailed dynamic imaging of swallowing disorders. Examination using electron beam tomography was done in three planes: (1) Passavant's cushion (n = 6), (2) thyrohyoid membrane (n = 9), and (3) upper esophageal sphincter (n = 5). The technique is discussed here in detail and documented with figures of the plane before swallowing as well as the intradeglutitive reachend plane. This study shows that electron beam tomography enables dynamic imaging of pharyngeal deglutition in transverse planes and can give useful additional information to the videofluorographic or kinematographic swallowing examination, which remain the gold standard in the functional evaluation of swallowing disorders.
