SAG T1 3D TSE/SPACE 1mm 0 mm 23cm Use same coverage/FOV as in our brain protocols
AXIAL T2 3D 23cm Use same coverage/FOV as in our brain protocols
AXIAL SWI 2D 2mm -1mm 20cm Use same coverage/FOV as in our brain protocols
COR orbits T2 mDIXON 2mm 0.25mm 18cm Cover from anterior margin of globe to anterior surface of pons
COR orbits T1 mDIXON 2mm 0.25mm 18cm Cover from anterior margin of globe to anterior surface of pons
HAND INJECT CONTRAST
+SAG FLAIR FS 3D 23cm Use same coverage/FOV as in our brain protocols
