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
Silicone screening
Position
Prone
Coil
Bilateral Breast Coil
Landmark
Mid-breast, Nipples

Contrast Agent Parameters

Contrast Agent Dose Injection Rate
Gadopiclenol (VUEWAY) 0.05 mmol/kg up to a calculated volume of 10 mL (If adding Routine Bilateral) 2 mL/sec
Saline Flush 20 mL 2 mL/sec
