Pediatric Brain 3.0T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • This exam is tailored to the patient’s condition and is meant for the needs of children under 8 years of age
• Take Fat Sat off for metal artifacts
• FOV and slice thickness should vary with head size
• Contrast as needed based on diagnosis
• Can use perfusion-weighted MRI or other sequences from adult protocols as needed
Position: Supine, head first
Coil: Head, HNU (Head 24 selected if possible)
Landmark: Glabella/Nasion

Contrast Agent	Dose	Injection Rate
Gadopiclenol (VUEWAY)	0.05 mmol/kg up to a calculated volume of 10 mL Gadopiclenol (VUEWAY) is approved for adult and pediatric patients, including term neonates. Safety has not been established in preterm neonates.	2 mL/sec
Saline Flush	10-20 mL	2 mL/sec
Comments	• Report agent administered and dose • Consider MPR 3 mm recons of all 3D sequences in all non-acquired planes
