Breast Bilateral Routine 1.5T
Philips Healthcare – MR Gadopiclenol (VUEWAY®) Protocols
Instructions And Patient Preparation
- Instructions
- • Ensure to increase the FOV as needed to include all breast tissue and axillae; use same FOV for all sequences
• Ensure to pull abdominal tissue down to prevent a fold into the coil and FOV
• Ensure to pull medial breast tissue into coil
• Ensure axilla tissue is in the coil and not above the side panel - Common Indications
- Diagnostic and screening
- Position
- Prone
- Coil
- Bilateral Breast Coil
- Landmark
- Mid-breast, Nipples
