Hyperacute Stroke Brain 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions And Patient Preparation

Instructions: • This exam is tailored to the patient’s condition and is meant for rapid assessment at lower resolution
• If perfusion-weighted MRI (PWI) or MRA Coronal is performed, a Power Injector should be used to administer contrast agent (split dose 1/3 MRA, 2/3 PWI)
• Contrast sequences provide superior resolution and image quality for MRA in the neck
Position: Supine, head first
Coil: GEM HNU or NVPA
Landmark: Glabella/Nasion

Contrast Agent Parameters

Contrast Agent	Dose			Injection Rate		Dose Timing Method and Scan Delay
Gadopiclenol (VUEWAY)	0.1 mmol/kg up to a calculated volume of 15 mL			Inject @ 4 mL/sec		Perfusion (DSC PWI) – Start scan and inject contrast after 12 sec of scanning
Saline Flush	20-30 mL			4 mL/sec		―
Comments	• Report agent administered and dose • Recon e3DPCA phase=vascular, magnitude=T1 all 3 planes 3 mm
