Abstract To explore the value of transvaginal three-dimensional ultrasound free anatomic imaging (OmniView) combined with color Doppler for differential diagnosing the benign or malignant ovarian tumors. Methods: The clinical data of 85 patients with ovarian tumor treated from January 2019 to December 2022 were collected retrospectively. Based on the surgical pathological results as the "gold standard", the diagnostic efficacy for the ovarian cancer was compared among the twodimensional ultrasonography, three-dimensional ultrasound, and the OmniView technology. The risk factors of the ovarian cancer were analyzed by logistic regression. Results: The maximum diameter of the ovarian lesion of the patients in group A was significantly higher than that of the patients in group B. The proportions of ystic/solid and inner wall with papillae of the patients in group A were significantly higher than those than those of the patients in group B. The resistance indexes values of ultrasonic parameters of the patients in group A were significantly lower than those of the patients in group B. The maximum systolic/minimum diastolic peak of blood flow velocities of the patients in group A were significantly higher than those of the patients in group B (all P＜0.05). Based on the results of pathology, the sensitivity, the specificity, and the accuracy of three-dimensional vaginal ultrasound, three-dimensional ultrasound combined with OmniView technology, and three-dimensional ultrasound combined with color Doppler for diagnosing the ovarian malignant tumor were 93.8%, 98.1%, 96.5%, respectively, which were significantly higher than those (84.4%, 81.1%, and 82.4%, respectively) of two-dimensional vaginal ultrasound, twodimensional vaginal ultrasound combined with OmniView technology, and two-dimensional vaginal ultrasound combined with color Doppler (P＜0.05). Logistic regression analysis showed that the independent risk factors of the ovarian malignant tumor included the internal echocystic or solid, the low resistance index value, and the high systolic peak/diastolic peak of blood flow velocity (P＜0.05). Conclusion: Transvaginal three-dimensional ultrasound OmniView technology combined with color Doppler has better value for differential diagnosing the benign or malignant ovarian tumors.
