Nomograms of vascularization indices of uterine health women, studyed with the use of three-dimensional energy dopplerography

Abstract

Differential diagnosis of benign and malignant tumors using the Doppler method is based on the fact that the blood supply of these tumors has its own peculiarities.The aim of the research is to study the nomograms of volumetric blood flow rates of the body and cervix of healthy women of different ages by means of three - dimensional angioplasty in search of differential diagnostic criteria for simple, proliferating leiomyoma and sarcoma of the uterus in the long term.Materials and methods. 157 practically healthy women were examined. The patients were divided into women of reproductive age, women in perimenopausal women and climacteric women. With the help of 3D uterine reconstruction using the energy mapping function and VOCAL (Virtual Organ Computer Aided Analysis), an objective assessment of the hemodynamics of the body and the cervix was performed by calculating the vascularization index (VI), which characterizes the percentage ratio of blood vessels to a certain extent tissues, blood flow index (FI), which characterizes the intensity of blood flow, which shows the volume of blood cells that move in the vessels at the time of the study and vascularization – flow index (VFI), which is an indicator of perfusion of the organ.Results. As a result, the nomograms of the volumetric blood flow (VI, FI, VFI) parameters of the uterus body were improved, and the nomograms of the volumetric blood flow (VI, FI, VFI) parameters of the cervix of healthy women were designed and the patterns of their changes depending on age were determined.The authors have established that the technique of three-dimensional echography-3D - reconstruction of the uterus in angiography with the use of the VOCAL option with the determination of volumetric blood flow parameters allows to objectively evaluate the degree of vascularization of the body and cervix of healthy women of all ages, preventing a subjective approach to assessing hemodynamics, which is present in the two-dimensional energy Doppler mapping mode.Conclusions. Based on the obtained results, the development of differential diagnostic criteria for benign, borderline and malignant tumors of myometrium with the determination of quantitative parameters of 3D – energy dopplerography will be based on the prospect, which will significantly increase the level of ultrasound diagnostics in gynecologic oncology and will allow to develop a rational tactic for treating patients
