Abstract Objective: To explore the value of transvaginal three-dimensional color power angiography(TV3D-CPA) in the diagnosis of ovarian tumors and determine the relationship between TV3D-CPA and clinical stages of malignant ovarian tumors. Methods: Sixty-five ovarian tumors(47 malignant ovarian tumors, 18 benign ovarian tumors) were examined with TV3D-CPA preoperatively, and the vascular index(VI) of tumors were determined. The difference in VI between benign and malignant ovarian tumors were analysed, and the relationship between VI and clinical stages were evaluated. Results: The VI of 47 malignant ovarian tumors with (0.08±0.052)counts/cm3 was higher than that of benign tumors with (0.043±0.031)counts/cm3(P<0.05). Using the VI≥0.035counts/cm3 as the cutoff, its sensitivity and specificity in detecting malignant ovarian tumors were 87.8% and 75%, respectively. VI in stage Ⅲ and Ⅳ (0.089±0.037)counts/cm3 was higher than that in stageⅠand Ⅱ (0.056±0.04)counts/cm3(P<0.05). Conclusion: TV3D-CPA was an effective method to indentify benign and malignant ovarian tumors by calculating VI. The higher the clinical stage was, the higher the VI will be, which might be an important index for predicting prognosis.
