However, any nucleus which has a net nuclear spin could potentially be imaged with MRI.

Hence partially occupied states, give a net spin up or down.

Particles having net spin include the proton, neutron, electron, neutrino, and quarks.

NMR spectroscopy uses the net spin of nuclei in a substance upon energy absorption to identify molecules.

NMR imaging also uses the net spin of nuclei (commonly protons) for imaging.

The difference in energy between all spins equal and nonstaggered but net zero spin is 4J.

Alpha particles, like helium nuclei, have a net spin of zero.

Transition metal atoms often have magnetic moments due to the net spin of electrons that remain unpaired and do not form chemical bonds.

The nucleus of an atom can also have a net spin.

It the atomic nucleus also has a net spin there is a further, but smaller contribution from it too.
