[Transvaginal color-coded Doppler ultrasound in XXXX ].

@entity1 @entity43 @entity5
In 129 @entity1 with @entity43 , a preoperative examination by transvaginal colour Doppler sonography (ATL UM9 HDI) was performed. 45 were malignant and 84 benign. 46 @entity1 were premenopausal and 83 postmenopausal. All @entity5 vessels were analysed by spectrum analysis. The number of @entity5 vessels and the lowest resistance index (RImin) and pulsatility index (PImin) of all vessels were evaluated as diagnostic criteria of the neovascularisation. Up to 19 vessels were found in 115 (89%) @entity5 . In benign lesions, the number of vessels was significantly lower than in @entity5 (median 3 versus 9, p < 0.0001). The RImin and PImin values between benign and @entity5 were also significantly different, independent of the menopausal status. In postmenopausal @entity1 , the median RImin in 42 @entity5 was 0.62 (0.26-1.0) and in 41 @entity5 0.40 (0.22-0.66). The median PImin was 0.98 (0.31-5.84) in @entity5 and 0.53 (0.25-1.22) in @entity5 . However, due to the overlapping range between benign and @entity5 , these parameters do not allow an accurate differentiation. With a cut off value for RImin = 0.5 and PImin = 0.7, the sensitivity is 85% or 82.5% respectively. The specificity for RImin and PImin is 77%, and the diagnostic accuracy is 84% and 80% respectively. The correlation coefficient between RImin and PImin is 0.99 in benign and @entity5 and both indices are adequate. The calculation of the RI is more easily available and should be preferred as a diagnostic parameter.
