MR Enterography 1.5T

Siemens Healthineers – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • Neural oral contrast such as 3 bottles of VoLumen (450 cc each) or 2 bottles of Breeza (473 cc each)
• Drinking oral contrast takes place over the course of one hour
• Patients should be NPO at least 4 hours prior to exam
• Use both Body Array coils
Common Indications: Crohn’s disease, abdominal pain, evaluate small bowel, malabsorption
Position: Supine, head or feet first
Coil: Body Array (2 coils, if possible), Spine Array (posterior)
Landmark: Xyphoid

Contrast Agent	Dose	Injection Rate
Gadopiclenol (VUEWAY)	0.05 mmol/kg	2 mL/sec
Saline Flush	20 mL	2 mL/sec
Comments	• Report agent administered and dose • Use minimal dose for patients with a GFR <30 mL/sec
