Abstract Treatment of oral and oropharyngeal cancer may cause dysphagia. Purpose is to examine whether cine mag-netic resonance imaging (MRI) yields additional information compared to standard examination in the evaluation of post-treatment dysphagia and mobility of oral and oropharyngeal structures. Thirty-four cine MRIs were made in 23 patients with advanced oral and oropharyngeal cancer, consisting of an MR image every 800 ms during swallowing which is compared to videoXuoroscopy and quality of life question-naires. A scoring system was applied to assess mobility on cine MR and videoXuoroscopy leading to a score ranging from 9 to 17. Cine MRI of the swallowing in a midsagittal plane visualized the tumor (if located in the same plane), important anatomic structures and surgical reconstructions. Posttreatment mobility on cine MRI and videoXuoroscopy was signiWcantly diminished compared to pretreatment, mean pretreatment cine MRI score was 10.8 and posttreat-ment 12.4 (p = 0.017). Impaired mobility on cine MRI was signiWcantly correlated to more swallowing problems (Spear-man’s correlation coeYcient 0.73, p = 0.04), on videoXuo-roscopy not. Cine MRI is a promising new technique as an adjunct to standard examinations for evaluation of swallow-ing in patients with oral and oropharyngeal cancer. Cine MRI directly visualizes the dynamics of swallowing and allows evaluation of pre- and posttreatment diVerences. Abnormal Wndings are signiWcantly correlated with subjective swallow-ing complaints of patients
