Abstract:
Objective To explore the value of apparent diffusion coefficient(ADC)value combined with ovarian-adnexal reporting and data system(O-RADS)MRI score in differentiating benign and malignant adnexal lesions with score 3-5.Methods The imaging data of 241 adnexal lesions with O-RADS MRI score 3-5 proved by pathology were analyzed retrospectively.The ADC values of all lesions were measured,and the optimal thresholds were determined by receiver operating characteristic(ROC)curve analysis,the comprehensive model was established using binary logistic regression analysis,the corresponding diagnostic efficacy was calculated.Results The median ADC values of the benign,borderline and malignant groups were 2.166 × 10-3 mm2/s,1.383 ×10-3 mm2/s and 0.839× 10-3mm2/s,respectively(P＜0.05).The area under the curve(AUC)of the combination of ADC value with O-RADS MRI score for differentiating benign and malignant adnexal lesions was 0.928[95％ confidence interval(CI)0.888-0.958],which was higher than that of O-RADS MRI score and ADC value alone(P＜0.05).The sensitivity and specificity of the three models in differ-entiating benign and malignant adnexal lesions were 93.5％,98.9％,83.9％,respectively;and 79.1％,58.8％,79.1％,respectively.Conclusion ADC value combined with O-RADS MRI score can be the most effective in the diagnosis of benign and malignant adnexal lesions,which is higher than O-RADS MRI score and ADC value.Compared with O-RADS MRI score,ADC value combined with O-RADS MRI score maintained good sensitivity and increased diagnostic specificity.
