Abstract:
Objective To investigate the MRI manifestations of ovarian tumors and their diagnostic value.Methods The MRI images from patients who underwent pelvic MRI examination,and who had ovarian space-occupying lesions confirmed by postoperative pathology were retrospectively collected.The diagnostic efficacy of MRI examination was compared.Results Pathological examination results showed that among the 208 patients with ovarian tumors,198 benign tumors were detected,including 35 cases of ovarian cysts,20 cases of mucinous cystadenomas,22 cases of plasma cystadenomas,41 cases of cystic/maturity teratomas,24 cases of fibromas/follicular membranous fibromas,and 56 cases of endometriotic cysts.The 10 malignant tumors included 5 cases of plasma cystadenocarcinoma,1 case of mucinous cystadenocarcinomas,1 case of sarcoma,and 3 cases of metastatic carcinoma.MRI was concordant with pathology in 197 cases,190 benign tumors were detected,31 cases of ovarian cysts,20 cases of mucinous cystadenomas,20 cases of plasma cystadenomas,41 cases of cystic/maturity teratomas,22 cases of fibromas/follicular membranous fibromas,and 56 cases of endometriotic cysts,and 7 malignant tumors(ovarian cancer)were detected.The MRI detection rate was 94.71％with a Kappa value of 0.869,which was in good agreement with the pathologic examination.The MRI examination demonstrated high diagnostic efficacy,with a sensitivity of 95.96％,an accuracy of 94.71％,and a positive predictive value of 98.45％,all of which in strong agreement with pathological examination results.Conclusion MRI examination and pathological examination have high concordance and high diagnostic accuracy in the diagnosis of ovarian tumors,providing imaging support for clinical identification of ovarian tumor types,and for doctors to provide diagnosis and treatment options.
