Abstract: In order to study the consistency of transvaginal three-dimensional ultrasound (3D-TVS) and magnetic resonance imaging (MRI) in the patients with endometrial carcinoma, 356 cases of endometrial carcinoma were selected as subjects. All patients accepted 3D-TVS and MRI before surgery. The consistency of preoperative assessment in endometrial cancer of these two methods were analyzed respectively from the tumor size, muscle layer infiltration, cervical infiltration, lymph node metastasis and tumor stage and so on. The results showed that the ICC of 3D-TVS and MRI on tumor diameter was less than 0.7, which indicated good consistency. The P values of preoperative evaluation of 3D-TVS and MRI on muscular layer infiltration, cervical infiltration, lymph node metastasis and tumor stage were all less than 0.05, suggesting that all Kappa values were consistent. The Kappa value of cervical infiltration was 0.913, showing a high consistency. In conclusion, 3D-TVS and MRI showed strong consistency in preoperative evaluation of patients with endometrial cancer, and both of them could provide effective reference for surgeons.
