The road less travelled: pushing the spatio-temporal limits of MRI at 3T
Magnetic resonance imaging (MRI) at 3T is the cornerstone for neuroscientific research due to its widespread availability. With the emergence of ultra-high field (≥7T) scanners, MRI has substantially pushed the limits of spatial and temporal resolution achievable. Recent advances in data acquisition and processing, coupled with insights gleaned from over 15 years of 7T MRI, have opened a new avenue for cognitive and clinical neuroscience research at 3T. This exciting, emerging domain leverages the capabilities of modern MRI scanners, incorporating new hardware and technologies that enable high acceleration, improved SNR, and spatial resolution to answer neuroscientific questions that were previously deemed not possible at 3T. For instance, recent demonstrations of sub-millimeter and sub-second resolution fMRI at 3T showcase results comparable to those obtained at higher field strengths.
