Contrast Agent Parameters

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
