Depth of myometrial invasion in endometrial cancer correlates with pelvic lymph node metastases and tumor recurrence. Thirty patients diagnosed as having FIGO stage I endometrial carcinoma on the basis of D&C were evaluated preoperatively by magnetic resonance imaging (MRI); 14 cases of the same group were also evaluated by transvaginal ultrasound. The degree of invasion evaluated by MRI and transvaginal sonography was compared to the pathological specimens. MRI was successful in evaluating myometrial invasion in 2.5 of 30 cases (accuracy 83%, sensitivity 87%, specificity 78%, positive predictive value 82%, negative predictive value 84%). Evaluation with transvaginal sonography was accurate in 11 of 14 cases (accuracy 78%, sensitivity 80% specificity 77%, positive predictive value 87%, negative predictive value 66%).
