Purpose: The pathophysiologies seen post head and neck cancer treatment were not fully understood. Videofluoroscopy, the gold standard for direct assessment of swallowing function, has its limitation due to the radiation exposure and the composite image of all anatomical structures. The purpose of this pilot study was to investigate the usage of real-time MRI to evaluate swallow function of tongue cancer patients.
Method (s): Real-time MRI of the midsagittal plane was collected on four male patients who were diagnosed base of tongue (BOT) or oral tongue (OT) squamous cell carcinoma and three gender/age-matched normal subjects.
