Tumor: 1st patient scan OR 1st post-op scan bilateral coronals and unilateral axials.
Routine follow up: scan unilateral coronals and unilateral axials

If hardware is present:

·         Do STIR instead of fat-sat mid-TE

·         If with Contrast, do non-fat-sat T1 post-contrast

Fat saturated images pre/post in both axial and coronal planes.
