Conclusion

3D ultrasound and 3D power Doppler have been proposed to improve the specificity in suspected stromal cervical invasion.

Exclusion of cervical canal involvement: hysterospcy. Predicting cervical involvement: MRI. In presurgical work-up of patients affected by

endometrial carcinoma hysteroscopy and MRI may both be useful for staging and planning the correct surgical strategy.
