| Abstract: | OBJECTIVES: To evaluate the usefulness of the measurement of angles of doppler wave spectrum in systolic phase in tumor vessels in adnexal masses and potential usefulness of this parameter in differential diagnosis of these lesions. MATERIAL AND METHODS: The study covers 173 patients with adnexal masses found on the examination. RESULTS AND CONCLUSIONS: The mean value of the measured angles in benign lesions amounted to 65.68 degrees and in malignant lesions 87.79 degrees. Additionally the readings of pulsatility index PI and flow speed: minimal -min, maximal -max and maximal mean -Ta ?r max. in examined vessels were taken into consideration. The statistically significant differences in the angle values of the two groups were noticed, although the usefulness of this single parameter in differential diagnosis of the lesions is not as helpful as usefulness of RI and PI but it is more useful than Ta min, Ta max and Ta ?r max. |
