MRCP 3T

Siemens Healthineers – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • NPO 4 hours, give patient one cup of pineapple juice prior to the scan
• Cover entire liver and pancreas
Common Indications: Biliary stones or obstruction, follow up of pancreatic cystic lesions
Position: Head or Feet first; Supine
Coil: Body Array (anterior); Spine Array (posterior) – Be sure ISO, AUTO-COIl SELECT is on
Landmark: Xyphoid. Center in the middle of body array coil. Table can be re-centered following the localizer

Contrast Agent	Dose	Injection Rate	Dose Timing Method and Scan Delay
Gadopiclenol (VUEWAY)	0.05 mmol/kg	2 mL/sec	Use CareBolus (CB) to track contrast to diaphragm; stop CB; perform breath hold (BH) command (~6 sec); start Arterial-phase acquisition
Saline Flush	20 mL	2 mL/sec	—
Comments	• Report agent administered and dose • Use minimal dose for patients with a GFR <30 mL/sec
