Prepolarized Magnetic Resonance Imaging is a long established technique conceived to counteract the loss in signal strength inherent to low field MRI systems. When it comes to hard biological tissues and solid state matter, PMRI is severely restricted by their ultra short characteristic relaxation times. Here we demonstrate that hard tissue prepolarization is possible with a 0.26 T scanner designed for dental MRI. These results can be applied to clinical dental imaging, making low field PMRI scanners a possible replacement for hazardous X ray systems.
