Assessment of ovarian tumors using transvaginal color Doppler ultrasonography.
In our study we used transvaginal color Doppler ultrasonography in a token of 127 women presenting with unilateral ovarian tumor. The characteristics of the tumors were analyzed, the presence of vascularization was checked and the resistance index (RI) was calculated. Consequently, based on a concrete scoring system, we attempted to discriminate these tumors as benign or malignant. It was proven that 24 of 127 ovarian tumors were malignant. Transvaginal color Doppler correctly identified 21 of the 24 malignant tumors, as well as 94 of the 103 benign tumors. In nine other cases we had false-positive results. The sensitivity and the specificity of the method was 87.5% and 91.2%, while the positive and negative predictive values were 70% and 96.9%, respectively.
