Angiogenesis in ovarian tumors

Transvaginal color and pulsed Doppler sonography can provide a superb image of pelvic organs and precise analysis of blood flow characteristic inside the observed vascular network. Vasodilatation of preexisting blood vessels and growth of newly formed blood vessels is a characteristic of almost all tumor tissues. Our goal is to determine weather three-dimensional power Doppler can recognize benign from malignant ovarian tumors according to measured resistance index (RI), where low RI refer to malignant lesions opposite to higher RI in benign ovarian tumors. During the recent period of time a number of benign and malignant ovarian tumors were histologically evaluated for presence of preexisting and newly formed blood vessels and our results are in good correlation with transvaginal color and pulsed Doppler measured resistance index.
