Objective  To investigate the clinical value of color Doppler ultrasound in diagnosing ovarian tumors.

  Methods  One hundred and fourteen cases diagnosed as ovarian tumors in Tianjin City Hospital of Gynecology and Obstetrics between April 2009 and April 2011 were selected. All of the patients were confirmed surgically and pathologically, and all the patients underwent color Doppler ultrasound. Comprehensive data were obtained from these patients.

  Results  These 114 patients with ovarian tumor diagnosed surgically and pathologically included 83 benign and 31 malignant ovarian tumor cases. Seventy-six patients were diagnosed with benign ovarian tumor using Doppler ultrasound, whereas 27 cases were diagnosed with malignant ovarian ttmaor. The diagnosis accordance rate was 90.35%. Statistically significant difference of 9.21% was found in the internal blood flow signal between benign and malignant ovarian tumor, processed by a statistical software (P < 0.05). The PI and RI were evidently different between the two groups. P-values were both less than 0.05, and the differences were both statistically significant. There was no evident or statistically significant difference in the PSV, HV, LV, MV, and S/D values between benign and malignant ovarian cancer patients (P > 0.05). Testing index: RI, PI, PSV, HV, LV, MV, and S/D.

  Conclusion  Color Doppler ultrasound is significant in the differential diagnosis of benign and malignant ovarian tumors.
