Abstract

Upper airway MRI can provide a noninvasive assessment of speech and swallowing disorders and sleep apnea. Recent work has demonstrated the value of high‐resolution three‐dimensional imaging and dynamic two‐dimensional imaging and the importance of further improvements in spatio‐temporal resolution. The purpose of the study was to describe a novel 16‐channel 3 Tesla receive coil that is highly sensitive to the human upper airway and investigate the performance of accelerated upper airway MRI with the coil. In three‐dimensional imaging of the upper airway during static posture, 6‐fold acceleration is demonstrated using parallel imaging, potentially leading to capturing a whole three‐dimensional vocal tract with 1.25 mm isotropic resolution within 9 sec of sustained sound production. Midsagittal spiral parallel imaging of vocal tract dynamics during natural speech production is demonstrated with 2 × …
