MRI scanning create a hugh amount of magnetic field, does anyone have any suggestions how this strong magnetic field will affect the orbits of electrons within atom?
Thanks in advance for any suggestions

Its not so much about the orbitals as it is about the particles' spin states, which lose their degeneracy within an external magnetic field. For electrons, this phenomenon is made use of in EPR spectroscopy; however it is limited to paramagnetic species (radicals, transition metals etc).

The Wikipedia pages about Nuclear Magnetic Resonance (NMR) and Electron Paramagnetic Resonance (EPR) spectroscopy have theory sections which describe the phenomenon.
