Abstract

Objective: To evaluate the possible advantages of a new combined technique that uses B-mode color maps, color flow imaging and Doppler waveform analysis simultaneously in the differential diagnosis of ovarian masses. Methods: Ninety-three ovarian lesions were detected by ultrasonograyhy and studied using the grey-scale map (GS), eight B-mode color maps (BC), color flow imaging (CD) and Doppler waveform analysis (DW) in 81 patients undergoing surgery. All diagnoses of ovarian tumour were confirmed by histopathology. Results: The use of BC facilitated morphological diagnosis as the morphology of different ovarian tumours was more clearly visible at BC than at GS with which the tissue texture was less well defined in some instances. However, ultrasound examination with BC was limited by an overlap between the gross morphology of benign and malignant tumours. Only about 25% of the benign tumours showed normal vascularity characterized by few and regular blood vessels, whereas all the malignancies had irregular, frequently abundant vascularity. Combining CD with BC improved the correlations between morphologic and vascular characteristics shown by different ovarian lesions and increased the number of correct diagnoses. When we evaluated impedance to blood flow we detected a significant difference between the resistance and pulsatility indexes (RI, PI) of benign and malignant tumours only when the lowest values for the central vessels were considered after analysis of multiple waveforms obtained in the same tumour. The efficiency of different ultrasound procedures was 83.7 (GS), 93.0 (BC), 97.8 (BC + CD), 94.8 (BC + CD + DW - RI) and 90.2 (BC + CD + DW - PI). Conclusion: The use of B-color maps significantly improved the evaluation of morphological characteristics of different ovarian tumours. The addition of color Doppler yielded sufficient morphological and vascular information for a correct diagnosis in most cases whereas the use of Doppler analysis proved to be of only slight benefit.
