MRI is unparalleled in its ability to non-invasively visualize anatomical structure and function with high spatial and temporal resolution and a broad range of clinical contrasts. The vast majority of clinical scanners incorporate superconducting magnets operating at 1.5, 3 and more exceptionally at 7T. At 6.5mT, more than 450 times lower than clinical MRI scanners, we demonstrate resolution in the living human brain in 6 minutes. We contend that robust non-field-cycled low-field implementations of MRI (< 10mT) have the potential to make clinically relevant images and set new standards for a completely new category of affordable robust portable devices.
