Magnetic resonance imaging (MRI) is an incredible invention and it has revolutionised how clinicians can diagnose serious diseases - because of its ability to create 2D slices through 3D objects and show different soft tissues.
It can also apparently be used to mess about with. For example, a blog HERE by Andy Ellison that shows dozens of animated serial section MRI scans through common or garden vegetables and fruits!
