Neonate Abdomen Dynamic Free-Breathing 3T

Philips Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions And Patient Preparation

Instructions: NPO 4 hours prior. Free-breathing. Cover top of liver through kidneys.
Position: Supine, head first
Coil: dStream Torso coil
Landmark: Center at mid abdomen

Contrast Agent Parameters

Contrast Agent	Dose	Injection Rate	Dose Timing Method and Scan Delay
Gadopiclenol (VUEWAY)	0.1 mL/kg (weight-based)	2 mL/sec	Free-breathing: allow one dynamic sequence to run, then start contrast injection
Saline Flush	15 mL	2 mL/sec	Following contrast
Comments	Dynamic contrast injection: 0.1 mL/kg by weight at 2 mL/sec, followed by 15 mL normal saline at 2 mL/sec. If the volume is too small for the power injector (typically less than 1 mL), place extension tubing and hand inject. Free-breathing dynamic sequence: allow one dynamic sequence to run and then start contrast injection.
