Objective To summarize the magnetic resonance imaging (MRI) features and to assess the diagnostic value of magnetic resonance imaging in endometrial carcinoma. Methods 72 patients with endometrial carcinoma comfirmed by surgery and pathology admitted into the hospital from March 2012 to March 2014 were selected as the research object. The clinical datum of the patients were retrospectively analyzed. According to the staging criteria of endometrial carcinoma made by international federation of gynecology and obstetrics (FIGO), the results of preoperative staging and postoperative pathology of the patients were compared and the MRI features and its diagnostic value of endometrial carcinoma were summerized. Results Among the 72 patients, there were 44 cases of stage I, 22 cases of stage II and 6 cases of stage III in preoperative MRI staging; 48 cases of stage I, 18 cases of stage II and 6 cases of stage III in postoperative pathologic staging; the coincidence rate of stage I was 91.67%, stage II 81.81% and stage III 100%. Conclusion In the clinical diagnosis and preoperative pathological staging of endometrial carcinoma, to adopt MRI scanning can accurately identify the degree of mesometrium invasion, range and prognosis with high preoperative staging rate. Compared with other diagnostic methods, it is simple to operate and of high accuracy. It can provide a reference for preoperative evaluation to optimize treatment effect, improving the prognosis of patients.
