Contrast Agent Parameters
| Contrast Agent | Dose | Injection Rate | ||||||
|---|---|---|---|---|---|---|---|---|
| Gadopiclenol (VUEWAY) | 0.05 mmol/kg | Hand injection or slow power injection (1-2 mL/sec is adequate) | ||||||
| Saline Flush | 20 mL | Hand injection or slow power injection (1-2 mL/sec is adequate) | ||||||
| Comments | Coronal Dynamic contrast-enhanced sequence is included as some small microadenomas may be better visualized on an early arterial phase; perform first phase of dynamic, pause built in, then restart scanner and start power injector at same time | |||||||
