Multiparametric ultrasound in the diagnosis of ovarian focal lesions

Abstract

Objective Development of an ultrasound diagnostic matrix for predicting the severity of proliferative changes in the ovarian focal lesion.Material and Methods The research was conducted on the basis of the Clinical Oncology Center, Regional Clinical Hospital no. 2. Echography (B-mode), color Doppler mapping, energy Doppler mapping (pulsation index, resistance index) on GE Voluson E8 and Aloka SSD 3500 devices were used as research methods. Retrospectively, 81 patients of reproductive age from 18 to 45 years were examined. Depending on the histological structure of ovarian lesion, the results of surgical treatment, dynamic observation and the outcome of the disease, were divided into 4 clinical groups: I (n = 12; 14,8%) – controls with no changes in the structure of the ovaries; II (n = 20; 24,7%) – patients with retention ovarian lesions; III (n = 20; 24,7%) – with benign tumors; IV (n = 29; 35,8%) – with malignant tumors.Results A large number of diagnostic parameters does not always allow to formulate an instrumental diagnosis correctly because they have different diagnostic significance. That is why we made an attempt to create a diagnostic matrix. For each of the 18 parameters, three answers were offered. When analyzing the results of the study, there was an increase in the number of pathological parameters from II to IV clinical groups. Thus, in group III, the combination of 2 pathological signs was found in 65% of cases, and 3 signs – in 25% of the examined women. In group IV, the combination of 2 signs was determined in 82% of the subjects, and 3 signs in 65%.Conclusion Thus, we found out that in-depth ultrasound examination (color Doppler imaging, pulsed Doppler) allowed to identify the severity of the proliferative changes and to give the prognosis of the disease.
