Pediatric Complete Spine Core 1.5T

Siemens Healthineers – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: Core imaging used on all pediatric spine protocols. Optional sequences added based on clinical indication.
Position: Head first supine
Coil: Head coil, Spine coil, and Body 18 (anterior)
Contrast Timing: T2 is performed immediately post contrast to allow time for peak contrast enhancement on T1 imaging.
Patient Preparation: Landmark per department pediatric protocol — pending sign-off.
Coverage and Technique Notes: • 3 PLANE HASTE LOC UPPER AND LOWER THEN COMPOSED
• SAG T1 FLAIR UPPER AND LOWER WITH SUBTRACTIONS OF PRE AND POST
• TRAN VIBE THROUGH ENTIRE SPINE (ANGLE WITH THE CORD AND USE SET AND GO PROTOCOL WITHOUT COMPOSING)

Contrast Agent	Dose		Injection Rate		Dose Timing Method and Scan Delay
Gadopiclenol (VUEWAY)	0.05 mmol/kg		Hand Bolus or Power Injection		Per department pediatric contrast protocol — pending technologist/radiologist sign-off.
Comments	• Use minimal dose for patients with a GFR <60 mL/sec • Report agent administered and dose
