Objective To analyze the clinical outcomes analysis of 3.0T MR in the diagnosis of patients with ovarian cystic lesions. Methods The clinical data of 40 cases of patients with ovarian cystic lesions who were treated in our hospital from May 2012 to May 2015 were retrospectively analyzed. Results Among the 40 cases of patients, 37 cases of patients were in the differential diagnosis in line with the results of pathology, the clinical diagnosis rate reached 92.5%, 15 cases of patients were with simple ovarian cysts, 8 cases of patients were with ovarian cystic teratoma, 6 cases of patients were with ovarian cystadenomas, 5 cases of patients were with ovarian endometriosis cysts, 3 cases of patients were with ovarian cystadenocarcinoma, 3 cases of patients were with ovarian cysts crown, accounting for 37.5%, 20.0%, 15.0%, 12.5%, 7.5%, 7.5% of the total, respectively. The average tumor /cyst diameters of ovarian cystic teratoma, mucinous cystadenoma, serous, crown cyst ovarian were (12.5±3.3) cm, (10.5±3.5) cm, (10.2±3.3) cm, (14.3±3.4) cm.
