Brain Neck MRA/MRV 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • Routine Brain sequences can be done in addition to sequences below. Exam consists of higher resolution sequences than the Stroke protocol
• The Neck TOF sequences are typically done only if the contrasted neck sequences are limited
• Injector recommended for CEMRA Coronal
• Contrast sequences provide superior resolution and image quality in the neck
• Inhance software useful for MRV sequences when needed
Position: Supine, head first
Coil: Head. If Neck is being imaged use NVPA or HNU
Landmark: Glabella or chin
