Pituitary 1.5T
Philips Healthcare – MR Gadopiclenol (VUEWAY®) Protocols
Instructions And Patient Preparation
- Instructions
- • Change patient into hospital issued gown and pants
• 20- to 22-gauge IV access preferred
• Power injector preferred - Position
- Supine, head first
- Coil
- 15 channel head coil

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 |
