MR Orbits WO Neuro Protocol

Coronal orbits coverage: Anterior margin of globe to anterior surface of pons, perpendicular to axis of the orbital segment of the optic nerves. 

Axial orbits coverage:  Superior margin of orbital rim to inferior margin of orbital rim, angled to be in-plane with the orbital segments of the optic nerves.
