MRI has become the preferred technique to study the dynamics of tongue and vocal tract during speech, singing or instrument playing. Recent advances provide access to qualitative information of fast tongue movements at very high temporal resolution. In this study, real-time MRI using highly undersampled radial FLASH with regularized nonlinear inverse reconstruction was used to monitor the dynamics of the tongue at 10 ms, 18 ms and 33 ms resolution. The effect of different temporal resolutions on the tongue and oral cavity during speech will be compared and analyzed.
