Orbits 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • 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
Position: Supine, head first
Coil: 8 channel Head or GEM HNU
Landmark: Glabella/Nasion

Contrast Agent	Dose	Injection Rate
Gadopiclenol (VUEWAY)	0.05 mmol/kg up to a calculated volume of 10 mL	Hand injection 1 mL/sec
Saline Flush	10-20 mL	Hand Flush
Comments	Report agent administered and dose
