Instructions And Patient Preparation

Instructions
• Change patient into hospital issued gown and pants
• 18- to 22-gauge IV access
Position
Supine, head first
Coil
15 channel head coil
Landmark
Glabella

Contrast Agent Parameters

Contrast Agent Dose Injection Rate
Gadopiclenol (VUEWAY) 0.05 mmol/kg 1-2 mL/sec
Saline Flush 10 mL 1-2 mL/sec
Comments • Do 3D T2 FLAIR precontrast and reformat in orthogonal planes
• T2 FLAIR postcontrast done to provide increased delay between contrast and Axial T1 postcontrast
