Current status of MR imaging of the female pelvis.

Magnetic resonance imaging (MRI) has become an important diagnostic method for the study of the female pelvis. It provides a noninvasive means of evaluating uterine zonal anatomy and can reflect the variable appearance of the female genital tract in response to different hormonal stimuli. It is considered a problem-solving technique for evaluating benign uterine and adnexal masses and is the primary imaging modality for staging endometrial, cervical, and vaginal carcinoma. It is also valuable in the assessment of vaginal agenesis and congenital uterine anomalies by providing information needed in surgical management. The role of MRI has not yet been established in the evaluation of ovarian carcinoma.
