In order to define the diagnostic outcome of cineradiographic examination of the swallowing act (pharyngeal stage) in patients with dysphagia, 250 such patients were consecutively examined at filmspeeds of 50 and 100 frames per second. Synchronous and symmetrical swallowing was observed in 20% of the patients while 80% exhibited functional abnormalities i.e., epiglottic dysfunction (33%), misdirected swallowing and aspiration (41%), cricopharyngeal dysfunction (22%), paresis of the pharyngeal constrictor musculature (10%), webs (15%) and Zenker diverticula (2%). These results clearly indicate that cineradiography can frequently disclose functional abnormalities in the act of swallowing among patients with dysphagia and explain the symptoms of these patients. Cineradiography is clearly superior to conventional single-film technique in revealing functional abnormalities in the act of swallowing.
为了明确吞咽困难患者吞咽动作（咽期）的动态放射学检查的诊断结果，对250例此类患者以每秒50帧和100帧的胶片速度进行了连续检查。20%的患者观察到同步且对称的吞咽，而80%的患者表现出功能异常，即会厌功能障碍（33%）、吞咽方向错误和误吸（41%）、环咽肌功能障碍（22%）、咽缩肌麻痹（10%）、蹼（15%）和Zenker憩室（2%）。这些结果清楚地表明，动态放射学检查能够频繁地揭示吞咽困难患者吞咽动作中的功能异常，并解释这些患者的症状。在揭示吞咽动作中的功能异常方面，动态放射学检查明显优于传统的单张胶片技术。
