Abstract Objective: To improve the recognition and diagnosis and differential diagnosis of MRI for female pelvic mass occupying diseases. Methods: To review the characteristics of MRI in 92 case of female pelvic occupying diseases(156 lesions) proved by pathology. Results: A total of 146 masses(146/156, 93.6%) were detected by MRI, including uterus diseases, 84 cases(84/85, 98.8%), ovarian diseases 61 cases(61/70, 87.1%) and rectal cancer 1 case, lesions not detected by MRI: 2 leiomyomas, 5 parovarian cysts and 3 corpus luteum cysts. For 146 masses, the location of 145 were consistent with pathology, the accuracy was 99.3%. Uterus diseases mainly demonstrated as solid tumor masses or endometrial thickening, ovarian diseases mainly demonstrated as cystic or cystic and solid or solid masses. In MRI, benign lesions were 108, malignant lesions were 38, while in the pathologic findings, benign lesions were 116, malignant lesions were 40, the sensitivity of MR in the diagnosis of malignant lesions was 95.0%(38/40), and the positive predictive value was 100%. Conclusion: MR can evaluate the origin of pelvic lesions with high accuracy as well as distinction between benign and malignant lesions, but there was some difficulty to diagnose cell types.
