Synopsis

MRI has enabled significant advances in our understanding of human speech production. This application benefits from a lower magnetic field due to reduced off-resonance effects at air-tissue interfaces. Here, we evaluate the SNR and parallel imaging performance of a dedicated speech coil at 0.55 Tesla, and compare it to that of a head-neck coil. Over the upper airway regions of interest, the dedicated coil shows approximately 1.3- to 4.6-fold improvement in SNR efficiency compared to the head-neck coil.
