"Advanced imaging technologies have enabled researchers to produce
3-D "magnetic resonance microscopy" (MRM) images of mice at more
than 250,000 times greater resolution than MRI scans used to diagnose
human disease. [...] In that scan, they achieved a resolution of 110 microns
of the whole mice, and could "zoom in" to scan individual organs at a resolution
of 25 microns. By comparison, the width of a human hair is about 200 microns."
