Instructions And Patient Preparation<\/h3>\n
\n
Instructions<\/dt>\n
• Reformat Sagittal T1 CUBE in Axial and Coronal planes. If CUBE is not available run Axial and Coronal T1 weighted sequences with and without contrast (+\/-Fat Sat)
• Axial T2 Fat Saturation or STIR used to assess optic nerve
• Axial CUBE or FIESTA images can be used to image the orbit and vessels
• This may be a standalone exam or an addition to a brain MRI
• Contrast is used for almost all examinations<\/dd>\n
