Abstract

Objective: To discuss MRI and color Doppler flow ultrasound imaging(CDFI) features of endometrial carcinoma and to evaluate MRI and CDFI in its preoperative staging. Materials and Methods: Preoperative MRI and CDFI of the pelvis were performed in 18 patients with pathologically proved endometrial carcinoma. The location of the lesion and the depth of mascular invasion were observed. The findings were compared with pathologic results. Results: MRI findings on T2WI usually included thickening of the endometrium, the signal was higher than muscular layer but a bit lower than adjacent remaining tunica intima and mucus in uterine cavity. The staging accuracy of MRI was 77.8%, and accurate evaluation of the depth of muscular invasion was 87.5%. CDFI findings included abundant color Doppler flow signal and low resistant blood flow in the focus. The staging accuracy of CDFI was 77.8%, accuracy of assessment of the depth of muscular invasion was 75%. Conclusion: MRI and CDFI can clearly display endometrial carcinoma and its extent and depth of involvement from different directions. MRI and CDFI have high value in the diagnosis of endometrial carcinoma transvaginal color Doppler sonography which has high resolution speciality, is a sensitive and simple way for screening endometrial carcinoma, but it is influenced by operators experience and other factors thus is inferior to MRI in clearly and directly displaying the depth of muscular invasion and metastatic nodules in adjacent structures. The diagnosis and staging accuraey of MRI and CDFI in endometrial carcinoma will be increased if these methods are combined in diagnosis.
