Results of MRI and IFS of the uterus for the evaluation of risk factors were correlated with final pathology.Results Our results showed a high specificity and negative predictive value of MRI and IFS for the evaluation of myometrial invasion and cervical stromal invasion. Of the 41 patients identified as low risk by both MRI and IFS, none had pelvic or para-aortic LN metastases in the final pathology.Conclusions The results indicate that MRI and IFS may be useful for the evaluation of risk factors associated with LN metastasis in patients with endometrial cancer. Magnetic resonance imaging and IFS can be used to accurately identify low-risk patients who do not need comprehensive surgical staging and may prevent unnecessary lymphadenectomy. ER -
