Instructions And Patient Preparation

Instructions
Position the head in the head coil and immobilize with cushions
Give cushions under the legs for extra comfort
Connect the anterior portion of the head coil and secure it in place.
Sedation vs bundle and feed is the ordering provider’s decision
Common Indications
Tumor
Optic nerve neuritis
Proptosis
Vision disturbance
Position
Head First
Supine
Coil
Head Coil 20ch
Landmark
Center over the glabella
Patient Population
These protocols are intended for smaller patients and serve as starting points. If a smaller FOV is needed, the parameters are modified accordingly.
