title: [Clinical value estimation of the Doppler indicies: PI, RI and PSV, TAMXV and MEDV in early differentiation of the ovarian tumors malignancy].
abstract: THE OBJECTIVES: The aim of this study was to evaluate the clinical value of blood flow indicies for differentiating between benign and malignant ovarian tumours.
  
  
  METHODS
  Realisation of the aim was based on the analysis of examinations' results of 686 ovarian tumors. For each recorded blood flow wave the followind parameters of examined tumor vessels were analysed: pulsatility index (PI), resistance index (RI), peak systolic velocity (PSV), time-averaged maximum velocity (TAMXV) and maximum and diastolic velocity (MEDV). Apart from conditional probabilities we also presented assessing areas under the ROC curves, which introducted information over practical usefulness of each test.
  
  
  RESULTS
  Vascular perfusion was observed in 100% of malignant tumors and 92% of non-malignant tumors. In group of patients with malignant tumors PI and RI were significantly lower; and PSV, TAMXV and MEDV were higher than in group with non-malignant tumors. (p<0.05)
  
  
  CONCLUSIONS
  Transvaginal ultrasonography with the Doppler technique is valuable diagnostic method in preoperative differentiation of tumor malignancies. The best predictive value in analysed group was observed for PI (AUROC=o.87) and MEDV (AUROC=0.86). Similar correlation was observed for premenopausal patients. In group of postmenopausal patients the best predictive value was for RI (AUROC=0.90) and MEDV (AUROC=0.88).
