Siemens Healthineers – MR Gadopiclenol (VUEWAY®) Protocols

Instructions And Patient Preparation

Instructions: • No special instructions for patient
• Cover kidneys and adrenal glands
Common Indications: Characterization or follow up of adrenal mass, suspicion of pheochromocytoma (refractory hypertension, elevated plasma or urine catecholamines)
Position: Supine, head first or feet first
Coil: Phase Array Torso, Spine Array (posterior)
Landmark: Xyphoid

Contrast Agent Parameters

Contrast Agent	Dose		Injection Rate		Dose Timing Method and Scan Delay
Gadopiclenol (VUEWAY)	0.05 mmol/kg		2 mL/sec		Power Injector preferred, CareBolus
Saline Flush	20 mL		2 mL/sec		—
Comments	• Radiologist to check pre contrast, to see if contrast is necessary; discretion of radiologist • Dixon Recons: In, Out, Fat, Water • Report agent administered and dose • Use minimal dose for patients with a GFR <30 mL/sec
