MR Face, Sinus & Skull Base WWO ENT Protocol

History of trigeminal neuralgia?

Use separate "Trigeminal Neuralgia" protocol. 

Coverage:

Sagittal: ear-to-ear, top of frontal sinus to hyoid bone and all of mandible, centered on posterior nasal cavity with FOV of about 180 x 180. Okay to exclude posterior neck/brain and superior brain.  

Coronal: Tip of nose to 4th ventricle, top of frontal sinus to hyoid bone and all of mandible. FOV about 180 FH and 150 LR.

Axial: Top of frontal sinus to hyoid bone and all of mandible. Centered on posterior nasal cavity with FOV of about 180 AP x 170 LR. Okay to exclude posterior part of brain and posterior neck.

Charge as: Parotid, Face, Sinus or Skull Base WO or WWO
Scanner preference: Avoid MR1, if possible.
Coil: NV
