Skull Base MRI Protocol

The "Skull Base MRI Protocol" is almost identical to the IAC/Temporal bone Protocols
Without Contrast "Skull Base MRI Sequences"

• Sag SE T1 
• Axial FLAIR
• Axial DWI 
• Axial EPI Gre-mainly on the area of interest/differentiate the calcification 
• Axial T1 3mm (bottom of pons to 3rd ventricle)
• Cor T2 FS 3mm (4th ventricle to post 1/3 of orbit)

Post contrast "Skull Base MRI Sequences"

• Ax T1 F.S.+C 3mm (skull base)
• Cor T1 F.S.+C 3mm (skull base)

Optional "Skull Base MRI Sequences"

• 3D FIESTA/CISS-heavily T2 weighted (If there is any associated pathology in the IAC/Temporal bone)

Technical notes in "Skull Base MRI Protocol"

• Fat saturation should be employed to better visualization of the pathological conditions. 
• Skull base starting at the cranial base.
