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 2.53.58.5mm3 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.
