Cardiac Basic Anatomy And Function 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions And Patient Preparation

Instructions: • Cardiac vector gating
• If coronaries are to be evaluated, reduce slice thickness to 5 mm and skip 0 mm for Double IR and Triple IR
• Respiratory bellows
• Breath hold all scans on expiration
Common Indications: Ischemic and non-ischemic cardiomyopathy (CMP)
Position: Supine
Coil: 8-32 channel Cardiac or GEMS Array
Landmark: Nipple Line

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			4 mL/sec		Injected during Perfusion. Consider injecting 1/3 the contrast for Perfusion and after the scan is finished inject the rest at a rate of 1 mL/sec
Saline Flush	50 mL			4 mL/sec		Immediately following gadolinium
Comments	Breath hold	3 Slice Mid Vent or if for Right Vent evaluation, then full stack copy and paste to acquire approx. 2 channel and 4 channel Locs	Short Axis, Double Oblique, Left Vent, Full Stack	Long Axis Views. 2 channel 3 channel 4 channel 3 Slices non-contiguous	Start scan, as soon as images start to appear, inject contrast at 4 mL/sec, once you visualize contrast have patient hold their breath for as long as they can	Inject contrast then wait 10 min for MDE. PREP TIME SCOUT–Use to determine TI time for MDE	10-45 min after injection. Delayed enhancement Short Axis and Long Axis views	Optional: 10-45 min after injection. Delayed enhancement Short Axis and Long Axis views	Optional: 10-45 min after injection. Delayed enhancement Short Axis and Long Axis views	Blood suppression must be done pre contrast	Blood suppression must be done pre contrast fat nulling
