Geeky, but fun. I'd like to see this with someone hung Good ol' MRI porn!

...For a challenge: We cannost see heavy water (with deutirium) in the same picture. Care to explain why?
Because the Larmor frequency is different for deutirium than it is with water. It has two protons, which changes the ratio of the magnetic dipole strenght vs the spin angular momentum of the nucleus. What do I win?Ah crap... I thought this woudl be interesting, but i am a chemist not a biologist. Nothing funky about these MRI images, which are actually spatial NMR (nuclear magnetic resonance). For the edification of the chemiscally inept, the iages are generated by looking at the hydrogen nuclei of water molecules.

The added proton of Deuterium changes the magnetic moment of the nucleus, and hence the resonant frequency.
big-D,Added proton? That would make deuterium an isotope of helium, which it ain't.
