Gynecologic Cancer Staging 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • Small FOV: Centered on uterus
• Large FOV: Renal vein level to symphysis; oblique axis refers to the tumor axis in the uterus (varies for endometrium vs cervix)
• Vaginal gel: 30-60 mL
• For metal artifacts consider reduced FOV multishot DWI, changing readout direction
Common Indications: Staging endometrial, cervical, vaginal, vulvar, ovarian/adnexal malignancy
Position: Supine
Coil: 32 channel Torso, GEMS Body array, or Air coil
Landmark: Iliac Crest

Contrast Agent	Dose			Injection Rate	Dose Timing Method and Scan Delay
