Afaik not really. The ones that scan humans are tuned for a specific proton resonance frequency, so they basically measure hydrogen density. But you get a 3D-Plot because they do a computed tomography of that density.
The chemistry NMRs are spectrographs, so you dial through a whole frequency spectrum and look at the reflected/transmitted signal. With that you get different peaks for different nuclei plus some deviations for crystal or molecular structure.
But I have to admit, that I'm a little rusty on that topic, so you might be right anyways.
Yeah right I looked again and also: MRI doesn't really work for highly conductive (bulk) samples: you can't get the RF in/out of the conductor due to skin effect.
