Comparison of the results of conventional ultrasonography and color doppler analysis in the evaluation of the nature of adnexal tumors. II. Color duplex doppler ultrasonography

The author evaluates the possibilities of coloured Doppler vaginosonography for prebioptic evaluation of the nature of ovarian tumours. He investigated the site of vascularization of tumours and qualitatively the blood flow by assessing the vascular resistance (PI, RI) and character of the flow velocity curve. The results revealed a statistically significant (p < or = 0.05) trend of central vascularization of malignant tumours. A new parameter with a 100% sensitivity and 89% specificity proved to be the notch at the beginning of the diastolic part of the velocity curve which was not observed in any carcinomas but was present in 89% of benign lesions. The vascular resistance was significantly lower in malignant tumours. The cut off value of malignity of the pulsatility index PI = 0.7 had a 86% sensitivity and 100% specificity. The cut off value of the resistance index RI is 0.6 with a 100% sensitivity and 75% specificity. Comparison of the predictive values of malignity of conventional and coloured duplex ultrasonography revealed that for evaluation of the nature of ovarian tumours coloured duplex sonography with several parameters is more suitable. PI and RI alone can be considered rather as indicators of active growth.
