The main results of the scientific activity of the Institute in 2020 are presented: the study of the structural features of diagnostic images based on their heterogeneity for the purpose of differential diagnosis of malignant neoplasms; development of radiation diagnostic criteria for differential diagnosis of congenital and acquired liver diseases in children; development of urgent detailed ultrasound examinations for traumatic injuries of the human body, complex radiation examination of the wound channel in case of a gunshot injury; development of methodological foundations for the use of multiparametric high-field MRI of the brain to assess the state of the leading tracts and the functional capacity of the cerebral cortex. Methods for textural analysis of computed tomographic images, echograms of normal and tumor tissues based on the use of coefficients of one-dimensional heterogeneity, anisotropy coefficient, and verticality coefficient have been developed. For the first time in Ukraine, a mathematical system that provides in 93-98% of cases of recognition of fibrous (precision) liver changes based on ultrasound images (utility model patent No. 139916) has been developed; significant differences between the values of mathematical criteria for normal and damaged liver based on computer processing of echographic images allow solving the problem of recognizing diffuse liver diseases.

Congenital malformations (CM) in fetuses and neonates belong to main causes of perinatal morbidity and mortality. Provision organs malformation and malfunction in such cohorts is less studied. The purpose - to analyze the course of pregnancy, the data of ultrasound imaging of provisional organs in the presence of CM of central nervous system (CNS) and/or of nephro-urinary system (NUS) in the fetus and newborn. Materials and methods. The results of prenatal and postnatal ultrasound, anamnestic and general clinical data of a sample of cases with prenatally diagnosed CM of CNS and/or NUS for the period 2017-2021 were analyzed. Results. There were 45 newborns with CNS malformations, and 54 newborns with CM of NUS. Malformations of NUS and/or CNS in the examined newborns were combined with anomalies of other systems in a third of cases - 29.6% and 31.1%, respectively. According to the results of prenatal ultrasound examinations, polyhydramnios (16.7%) was most often recorded in the pregnancies with fetal CM of NUS, and cases of fetal CM of CNS most commonly were registered placental hyperplasia (35.6%), fetal growth retardation (24.4%) and fetal distress (26.7%). Postnatally in both cohorts (with NUS malformations and with CNS malformations) a high rate of following complications were recorded: prematurity (16.7% and 15.6%, respectively), birth asphyxia (48% and 55.6%, respectively), and early neonatal death (11% and 6.6%). Сonclusions. Pregnant women with CM of CNS and/or NUS in the fetus belong to the group of high perinatal risk because of the high rate of perinatal complications. Information about the identified high perinatal risks in fetuses and newborns with CM of the CNS and/or NUS should be provided to parents and taken into account when planning management of pregnancy and labor.

Respiratory distress is one of the most common causes of neonatal morbidity and mortality. The aim of this study was to determine perinatal factors and ultrasonographic features of newborn respiratory disorders. We examined 49 children aged 0-28 days who had manifestations of type 1 RDS (group 1 – 24 children) and pneumonia caused by intrauterine infection or massive meconium aspiration syndrome (group 2 – 25 children). The control group consisted of 20 newborn. The control group consisted of 20 newborns. Data analysis showed that the presence of extra genital pathology that had mother, significantly influenced on the development of respiratory disorders (group 1 – 75 % ,and group 2 – 60 % compared to the control group – 20 %), as well as a high frequency of chronic fetal hypoxia and placental dysfunction complicated by fetal distress (in group 1 – 75 % of cases, in group 2 – 40 %) It was found that ultrasound examination of the lungs is an informative, safe method for diagnosing pneumonia, pneumothorax, the presence of fluid in the pleural cavity of newborn respiratory disorders, and provides an opportunity to monitor pathological changes during treatment.
