Routine Stroke Brain 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • The Neck TOF sequences are typically done only if the contrasted neck sequences are limited
• If perfusion-weighted imaging (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: Head. If Neck is being imaged use NVPA or HNU
Landmark: Glabella/Nasion

Contrast Agent	Dose	Injection Rate	Dose Timing Method and Scan Delay
Gadopiclenol (VUEWAY)	0.15 mmol/kg up to a calculated volume of 20 mL	TRICKS – inject 0.1 mmol/kg (max 15 mL) @ 1.5 mL/sec Perfusion (DSC PWI) – 0.05 mmol/kg (max 5 mL) @ 4 mL/sec	TRICKS – Scan Mask, Scanner Pauses, Inject contrast, wait 5 sec, then start scan Perfusion (DSC PWI) – Start scan and inject contrast after 12 sec of scanning
Saline Flush	20-30 mL	TRICKS – 1.5 mL/sec Perfusion (DSC PWI) – 4 mL/sec
Comments	Report agent administered and dose
