MR Brain and Orbits WO Neuro Protocol
Orbits Only Coronal Coverage: Anterior margin of globe to anterior surface of pons, perpendicular to axis of the orbital segment of the optic nerves.
Orbits Only Axial 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.
Whole Brain Sagittal Coverage: Angle to interhemispheric fissure. Cover at least 1cm above vertex through skull base. Cover entire nose.
Whole Brain Axial Coverage: Angle to corpus callosum. Cover at least 1cm above vertex through skull base. Cover entire nose.
