Cavernous Sinus Protocol (MR& CT).

Cavernous Sinus Protocol (MR& CT). 

A) MR Protocol:

• Routine T2.
• Flair.
• Pre contrast T1 for the entire brain.
• Post contrast T1 equal or less than 3 mm- thick images in axial and coronal planes with at least one plane imaged with a fat saturation technique.
• Images taken from orbital apex to pre pontine cystern.
• Thin section 3 D heavily weighted images may allow visualization of cranial nerves in cavernous sinus  and adjacent cysterns. 

B) CT Protocol:

• Multi detector machine.
• Post contrast images.
• Axial or coronal planes by using 1mm or less thick section.
