Pituitary 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • Exam consists of Sagittal and Coronal T1 weighted sequences with contrast and without contrast
• Dynamic contrast may be needed for some applications
• This may be a standalone exam for follow-up or add sequences from Routine Brain protocol
• Contrast is used for almost all examinations
• Post-contrast Coronal Fat Saturation sequence can help in the postoperative patient
Position: Supine, head first
Coil: Head, HNU (Head 24 selected if possible)
Landmark: Glabella/Nasion

Contrast Agent	Dose	Injection Rate	Dose Timing Method and Scan Delay
Gadopiclenol (VUEWAY)	0.05 mmol/kg up to a calculated volume of 10 mL	Hand injection 1 mL/sec For Dynamic – Power injection 2 mL/sec	Post Coronal T1 should be imaged immediately after contrast
Saline Flush	Hand injection 10-20 mL	Dynamic 20-30 mL saline 2 mL/sec	―
Comments	Report agent administered and dose
