Introduction. Most patients with early-stage endometrial carcinoma are treated with hysterectomy. The knowledge of the stage of disease could impact greatly on the eventual therapeutic decision. Numerous studies have investigated the use of endovaginal ultrasonography (US) and magnetic resonance (MR) imaging in the preoperative staging of endometrial carcinoma. Although a number of studies have demonstrated no significant difference in the accuracy of MR imaging and endovaginal US in assessing myometrial invasion, more recently, dynamic contrast-enhanced MR imaging has been found to be significantly superior to the non-enhanced T2-weighted MR imaging in the preoperative evaluation of endometrial carcinoma. Purpose. (1) To evaluate prospectively the relative accuracy of endovaginal US (including Doppler) and MR imaging using phased array pelvic multicoil in the preoperative staging of endometrial carcinoma with histopathological correlation on the same patient population, (2) To determine whether the addition of contrast-enhanced MR sequences to high resolution fast spinecho (FSE) T2-weighted sequences, can improve the diagnostic accuracy of staging endometrial carcinoma.
