Doppler characteristics of benign and malignant ovarian tumours

ABSTRACT

This study included 30 patients in whom ovarian masses were detected by sonography, at time of routine gynaecological examination, the cases were subjected to Detailed history taking, full general and gynaecological examination, transvaginal sonography [TVS], transabdominal sonography [TAS], sonographic scoring for every ovarian mass, Doppler imaging for the entire tumour to detect area of neovascularization, pulsatility index [PI] and resistive index [RI] for ovarian masses, also histopathological examination of the masses after laparotomy was done. It is found that the accuracy to differentiate benign from malignant tumours was; clinical examination equal 63%, transabdominal sonography equal 76.7%, transvaginal sonography equal 80%, Doppler indices, PI equal 86.7%, RI equal 90%, combination between TVsS and RI equal 96.7%. The combination of TVS scoring of ovarian masses with RI cut off value representing superior flow Doppler parameter, can carry better prediction of malignancy
