Instructions And Patient Preparation<\/h3>\n
\n
Instructions<\/dt>\n
• Reformat Sagittal T1 CUBE and Coronal 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 CUBE FOCUS or FIESTA images are used to image the cranial nerves
• This may be a standalone exam for follow-up or done in conjunction with sequences from Routine Brain protocol
• Contrast is used for almost all examinations<\/dd>\n
