Runoff Abdomen To Lower Extremity MRA 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions And Patient Preparation

Instructions: Coil coverage from toes to diaphragm
Common Indication: Peripheral arterial disease (PAD)
Position: Toes should be inside bottom edge of coil
Coil: GEMS Peripheral Vascular (PV) Coil with Anterior Array and Posterior Array
Landmark: Landmark where you center the Body Array Coil

Contrast Agent Parameters

Contrast Agents	Dose			Injection Rate		Dose Timing Method and Scan Delay
Gadopiclenol (VUEWAY)	0.075 mmol/kg up to a calculated volume of 10 mL OK to cap at 20 mL max volume Dilute to 30 mL			See specific instructions below for Calf and Thigh stations		For Abdomen Station: Fluoro trigger to peak arterial opacification at level of bifurcation 2 mL/sec
Saline Flush	60 mL			See below		2 mL/sec immediately following gadolinium
Dynamic Notes	TRICKS timing: 1. Start scan 2. Mask runs as clock counts down 3. Inject at 0:00 4. Clock will reset 5. Scan will continue to acquire multiple phases			Calf TRICKS contrast: 1.5 mL/sec = 8-10 mL Thigh TRICKS contrast: 1.5 mL/sec = 10-12 mL Flush: 1.5 mL/sec = 20 mL Flush: 1.5 mL/sec = 20 mL		Foot-mid Calf: I200-S82, 30 x 22 Calf-low Thigh: S76-S380, 30 x 22 Thigh: S372-S654, 36 x 36 Pelvis-Abdomen: S642-S948, 36 x 36 Abdomen-Diaphragm: S918-> PRN
