ARDL Spine 1.5T Sequences

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions And Patient Preparation

ARDL: • ARDL is available on recent upgrades to GE scanners
• ARDL is a denoising technique
Notes: • Like any protocol update, each radiology department will need to test any change to protocol and get chief radiologist approval prior to implementing
• Recent upgrades to GE scanners removed the imaging option “No Phase Wrap (NPW)” and now has a “NPW Factor” that can be reduced or increased to prevent wrap
• ARDL is available for Propeller and CUBE sequences at 30.0

Contrast Agent Parameters

Contrast Agents	Dose				Injection Rate
Gadopiclenol (VUEWAY)	0.05 mmol/kg up to a calculated volume of 10 mL				Hand Bolus
Saline Flush	10-20 mL				Hand Bolus
