Abstract To explore the value of two-dimensional ultrasound combined with color Doppler flow imaging (CDFI) for diagnosing the benign or malignant ovarian lesion. Methods: A retrospective analysis was performed on the clinical data of 131 patients with ovarian tumors between April 2018 and April 2021. These patients were divided into group A (cases with benign ovarian tumors) and group B (cases with malignant ovarian tumors) based on the histological examination results of the patients. In order to obtain the mean value, range, and distribution of the ovarian RI value of the patients, the ultrasound morphological structure and blood flow status of ovarian masses of the patients were analyzed by two-dimensional ultrasound and CDFI. The detection situations of ovarian benign lesions of the patients by two-dimensional ultrasound and CDFI were counted. The diagnostic efficiency of two-dimensional ultrasound or CDFI for ovarian tumors was calculated. Results: Among 131 patients with ovarian tumors, there were 86 cases with benign ovarian tumors, mainly including serous tumors and ovarian endometriosis, and there were 45 cases with malignant ovarian tumors, mainly including mainlyepithelial ovarian cancer. Ultrasound morphological analysis showed that the benign ovarian tumors were the manifestations of simple unilocular and simple multilocular mainly, and the malignant ovarian tumors were the manifestations of unilocular cyst combined with nipple manifestation mainly. There were 24 patients without blood flow signal in benign tumors of 86 patients, and there were 45 patients with blood flow signal in malignant tumors of 45 patients. The RI value of the patients in group B was 0.41±0.10 (0.25-0.64), which was significantly lower than that [0.53±0.11(0.33-0.74)] of the patients in group A (P<0.05). Receiver operating characteristic (ROC) curve analysis showed that the area under the curve and the cut-off value of RI value for distinguishing benign and malignant ovarian tumors of the patients were 0.794 and was 0.46. The sensitivity, the specificity, and the accuracy of two-dimensional ultrasound combined with CDFI for diagnosing benign or malignant ovarian lesions of the patients were 97.8%, 76.7%, and 84.0%, respectively. Conclusion: There are significant differences in the manifestations examined by two-dimensional ultrasound and CDFI between benign and malignant ovarian tumors in B-US and CDFI. The combined application of two-dimensional ultrasound and CDFI has good differential diagnostic efficiency for benign or malignant ovarian lesions.
