Spatiotemporal resolution requirements for various speech tasks. The placement of these “zones” reflects the current consensus opinion among speech imaging researchers in attendance at the 2014 Speech MRI Summit. Boundaries are approximate due to the lack of gold-standard imaging techniques, and are being refined through the more widespread adoption of noninvasive techniques such as RT-MRI. The plots depict the spatiotemporal resolutions that could be realized by the four recommended protocols in Table 1. Note that each of the protocols have tradeoffs beyond spatial and temporal resolutions, which require careful consideration and are discussed in detail in the text. For instance, SNR losses at high spatial resolutions (all protocols), off-resonance artifacts (Protocol 2), long acquisition times (Protocol 4).
