The "Skull Base MRI Protocol" is almost identical to the IAC/Temporal bone Protocols
Without Contrast "Skull Base MRI Sequences"
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)
- Ax T1 F.S.+C 3mm (skull base)
- Cor T1 F.S.+C 3mm (skull base)
- 3D FIESTA/CISS-heavily T2 weighted (If there is any associated pathology in the IAC/Temporal bone)
- Fat saturation should be employed to better visualization of the pathological conditions.
- Skull base starting at the cranial base.
