Stage 1: tumor confined to uterus
|
- 1a.
- Disruption or irregularity of the low T2 signal junctional zone
- Disruption of subendometrial early enhancement

- Disruption or irregularity of the low T2 signal junctional zone
- Disruption of subendometrial early enhancement

|
|
Stage 2: tumor extends to cervix
|
- Widening of internal os and endocervical canal by high/isointense T2W signal tumor mass.
