sagittal
Sagittal planning
- Cover the entire brain from left to right.
- Cover from the top of the brain through the C2 level.
- Cover from temporal bone to temporal bone.
- Align parallel with the longitudinal fissure.
Neuro protocol
Combined brain and orbital MRI for proptosis, diplopia, vision loss, ptosis, vascular orbital lesions, and optic nerve disorders. Includes full brain workup plus dedicated thin fat-saturated orbital sequences and 3D T1 with reformats.
For protocol planning and internal reference only. Follow institutional MRI safety screening, contrast, dosage, and GFR policies.
