MR Brain and Orbits WWO 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.
