  • Analysis of blood flow in adnexal tumors by using color Doppler imaging and pulsed spectral analysis
    Takač, Iztok
    Because of various contradictory reports in the literature and an increasingly urgent need for preoperative evaluation of adnexal masses before laparoscopic surgery, our aim was to disclose if ... examination by means of color Doppler ultrasound is useful in distinguishing benign from malignant adnexal tumors in our population. Prior to surgery, pulsed color Doppler velocimetry of the adnexal blood supply was preformed in a prospective study in 80 patients with benign and 40 with malignant adnexal tumors. Vascularization was equally frequent in both groups of tumors. Blood vessels of benign tumors had a diffuse, intraseptal or intraproliferative location significantly more often and malignant tumor vessels more often exhibited a diffuse, intraseptal or intraproliferative location (p<0.01). The mean value of RI +-SD was 0.56+-0.14 in benign and 0.33+-0.13 in malignat tumors. The differences in RI between bening and malignant tumors are statistically significant (p<0.01). In detecting malignant adnexal tumors, the sensitivity of RI<0.40 is 82%, its specificity 97%, positive predictive value 94%, negative predictive value 92% and its accuracy 92%. The analysis of vascularization presence seems not to have any value in predicting the nature of adnexal tumors, and bood vessels arrangement, as well as measured RI<0.40, allows us to predict the presence of malignancy with limited reliability.
