This study aimed to evaluate the accuracy of magnetic resonance imaging (MRI) in the detection of deep myometrial invasion and cervical extension by endometrial carcinoma. We also aimed to compare MRI results to surgical staging of endometrial carcinoma. Forty women with a histologic diagnosis of endometrial carcinoma underwent a preoperative pelvic MRI. In 33 cases intraoperative gross visual inspection (GVI) of the surgical specimen was also evaluated. The results obtained were compared with the histologic diagnosis. Pathologic evaluation of the myometrium determined that superficial invasion was present in 25 patients and deep invasion in 15. The uterine cervix was found to be involved in 12 cases. The accuracy, sensitivity, and specificity of MRI and GVI were 93%/91%, 80%/77%, and 100%/100%, respectively, in detecting deep myometrial invasion and 80%/79%, 33%/36% and 100%/100%, respectively, in determining cervical invasion. When the Kappa statistical measurement was applied, the results from each technique, MRI and GVI, showed an agreement on the evaluation of myometrial and cervical invasion by endometrial carcinoma. In conclusion, MRI, in this series, was demonstrated to be a reliable method for preoperative endometrial carcinoma “imagiological staging”. The high accuracy achieved by MRI and GVI suggests that they may be used interchangeably.
