Important MRI Findings for Gynecological Cancer

Cancer	Finding	Reason
Cervical	Parametrial extension	Stage IIB: Nonsurgical. Radiation ± chemotherapy
Cervical	Pelvic side wall invasion	Stage IIIB: Poorer prognosis
Endometrial	Deep (>50%) myometrial invasion	Stage IB*: Increased (~50%) risk of nodal metastases. Will need radical lymph node resection.
Endometrial	Cervical stromal invasion	Stage II*: Requires preoperative radiation therapy or a different surgical plan (i.e., radical hysterectomy instead of total abdominal hysterectomy)
