Object: To apply different scores proposed by the literature in the Doppler transvaginal ultrasonography findings (TV US) and to demonstrate their utility in the characterization of ovarian tumors. Material and method: From January 2003 to December 2005, a total of 2308 patients were studied by TV ultrasonography. In this group, 144 women presented ovarian tumors, to whom a Doppler TV was performed. The Doppler findings were retrospectively reviewed applying the De Priest's Morphology Index (IM), the Alcazar's Scoring System and the morphologic study of the ovarian tumor. As suggestive of malignancy an IM? 5 was considered. For Doppler parameters, an IR < 0,45 and a velocity ?10 cm/sec were considered as cutting value. Results: The combination of morphological and spectral analysis showed a sensitivity (S) of 86%, a specificity (E) of 89%, a predictive positive value (PPV) of 0,46 and a predictive negative value (PNV) of 0,98. De Priest's score yielded the following results: S= 89%, E= 73%, PPV= 0,46 and PNV= 0, 96. Applying the Alcazar's score, the results were: S= 75%; E= 84%, PPV= 0,21, PNV= 0,98. The different scores showed a fluctuating rate of false positive: between 11 and 37%. Conclusions: In the evaluation of ovarian tumors, the Doppler ultrasonography presents high sensitivity and PNV, moderate specificity and poor PPV for malignant lesions. Therefore, a negative result is highly reliable for benignity, while a positive result must be caustiously interpreted in front of his possible surgical resolution.
