Pushing the spatiotemporal resolution using spiral acquisition has been an active area of research in dynamic speech imaging. However application of long readout spirals at high field have been limited by off-resonance blurring around the mouth and airway. Low field MRI offers an advantage to speech imaging, due to reduced local susceptibility gradients. Here, we demonstrate reconstructions of single shot spiral (up to 9.4 ms readouts) without accruing any blurring artifacts resulting in high temporal resolution (11 ms) dynamic speech imaging.
