Dynamic speech MRI has seen increasing use in the clinic for cleft palate and oral cancer and in research for examining the articulatory patterns of speech. Although potential frame rates have increased, in order to optimize acquisitions, special RF coils may be required to match the anatomy of the population of interest. In this work, we examine the potential of low-cost dielectric pads to significantly improve the SNR of acquisitions using standard head/neck coils. We show a 20% improvement in SNR in speech articulator regions with two dielectric bags placed on either side of the face.
