[Abstract] Objective To investigate the magnetic resonance signal characteristics of benign and malignant ovarian lesions with short T1 signal and the diagnostic value of apparent diffusion coefficient (ADC) value.Materials and Methods A total of 42 patients with benign and malignant ovarian lesions confirmed by surgery and pathology in the Affiliated Hospital of Qinghai University from Jun 2019 to Jun 2020 were selected and their T1WI images were analyzed. Imaging signs were observed and the maximum diameter, ADC value, tumor location, boundary, cystic firmness, cystic wall/space, and T1 signal uniformity were measured to compare the differences between the two groups.Results There were 52 T1 hypersignal lesions in 42 patients. Among them, 39 lesions were benign, including 16 endometriosis cysts, 10 mature cystic teratoma, 7 luteal cysts, 4 mucinous cystadenoma, 1 white body and 1 follicular cyst with hemorrhage. Thirteen lesions were malignant, including 11 serous cystadenocarcinoma, 1 clear ovarian cell carcinoma and 1 granulosa cell tumor. There were statistically significant differences in the maximum diameter, ADC value, capsule wall/space, cyst consolidation and T1 signal uniformity between benign and malignant lesions (P＜0.05).Conclusions Magnetic resonance imaging has a certain value in differential diagnosis of benign and malignant ovarian lesions with short T1 signal, and the accuracy of preoperative determination of ovarian lesions can be improved by mastering the MR characteristics.
