Routine Adult Brain 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions And Patient Preparation

Instructions: • Contrast is used for assessment of the blood-brain barrier, infection, tumor, and some stroke evaluation
• T2* GRE susceptibility sequence used for trauma, evaluation for blood, and seizure cases
• Perfusion sequence is optional in stroke or tumor cases
Position: Supine, head first
Coil: Head, HNU (Head 24 selected if possible)
Landmark: Glabella or chin

Contrast Agent Parameters

Contrast Agent	Dose				Injection Rate
Gadopiclenol (VUEWAY)	0.05 mmol/kg up to a calculated volume of 10 mL				Hand Bolus usually For perfusion-weighted imaging (PWI), Use 0.1 mmol/kg up to a calculated volume of 15 mL @ 4 mL/sec
Saline Flush	10-20 mL				—
Comments	• Report agent administered and dose • Consider MPR 3 mm recons of all 3D sequences in all non-acquired planes
