Value Of MRI In The Assessment Of Invasion By Endometrial Carcinoma

Objective:To evaluate the value of MR imaging in the assessment of invasion in endometrial carcinoma.Methods:The data of 46 patients with endometrial carcinoma proved by postoperative pathology were retrospectively reviewed.all patients underwent conventional MRI examination Preoperatively .Compared with the results of pathology, The sensitivity, specificity and accuracy respectively of MRI in evaluation the invasion in endometrial carcinoma determined by MRI were analyzed .Result:1)Based on MR image, the tumor was confined to the endometrium in 8 patients, superficial myomentrial invasion in19, deep-myometrial invasion in 12 and having penetrated the serosa in 7.Compared with postoperative pathology results, the incidence of sensitivity, specificity and accuracy of MRI assessment for tumor confined to endometrial was 75%?94.7%and 91.3%, respectively.to superficial myometrial invasion:80%?88.5%and 84.8%, respectively.to deep-myometrial invasion: 81.8% ? 91.4%and 89.1%, respectively.to tumor having penetrated the serosa: 71.4%?94.9%and 91.3% respectively.2)Based on intact junctional zone as the criterion of tumor confined to endometrium, the sensitivity, specificity, accuracy, positive and negative predictive value was 75%?92.6%?88.6%?75%?92.6%, respectively .3)Based on the interruption of junctional zone as the criterion of tumor having involved the myometrium, the sensitivity, specificity, accuracy, positive and negative predictive value was 92.6% ? 75% ? 88.6% ? 92.6% ? 75%, respectively Conclusion:MRI is one of valuable methods in the assessment of the invasion in endometrial carcinoma, and could plays an important role for the clinical in selecting proper therapy.
