Acceleration techniques necessary for real-time MRI of swallowing and diffusion imaging of the tongue require multiple coil elements and decrease SNR. Therefore, we designed a 12-channel flexible tongue coil with a higher density of elements compared to the conventional head and neck coil. The SNR in the tongue coil is better, while the G-factor is lower compared to the conventional coil. Real-time MRI displayed better image quality with fewer radial streaking artefacts using the tongue coil. A multiband-SENSE factor of 2 was feasible for diffusion-weighted imaging with the tongue coil.
