Epilepsy Brain 3.0T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions And Patient Preparation

Instructions: • New onset seizures should be performed as Routine Brain with/without contrast
• Coronal Oblique perpendicular to temporal lobe/hippocampus
• This exam is performed in addition to some Routine Brain sequences. Axial GRE T2*W sequence required
• Contrast can be used for adult examinations
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
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 • Hi Res Coronal or Axial STIR for Cortical Dysplasia or Mesial temporal Sclerosis
