A special sensor provides a three-dimensional image of the object under study, which sends a signal to the computer. There, a special program converts a flat two-dimensional image into a three-dimensional one.<\/p>\n\n<p>4D ultrasound &#8211; a three-dimensional image is supplemented by another dimension &#8211; time, which allows you to observe the movements and movements of the object under study in real time.<\/p>\n\n<p>With the help of advanced ultrasound capabilities, a pregnant woman can see the face, movements and facial expressions of the unborn baby. The most optimal time for such a study is 20-26 weeks of gestation. During this period, the size of the fetus allows it to fit comfortably enough in the uterus, and the amount of amniotic fluid provides freedom of movement.<\/p>\n\n<p>In addition, the baby&#8217;s facial features are already clearly visible and all external organs are formed. At a later stage, the grown fetus needs to take a special position to fit into the bubble, and it will be much more difficult to see the baby&#8217;s face.<\/p>\n\n<p>3D and 4D cannot completely replace conventional two-dimensional ultrasound and are an addition to the standard examination.<\/p>\n\n<p>Innovative research methods allow:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>to establish a psycho-emotional connection between parents and their child before the child is born;<\/li>\n\n\n\n<li>determine the sex of the child and who he or she looks like;<\/li>\n\n\n\n<li>identify abnormalities in the development of various parts of the body.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Indications for the appointment of 3D and 4D ultrasound<\/h2>\n\n<p>Pregnant women can undergo 3D and 4D ultrasound at the Rodynne Dzherelo Medical Center at their request or as prescribed by a doctor. Indications for the procedure are:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>various diseases suffered by a pregnant woman during the gestational period, which can negatively affect the formation and development of the fetus;<\/li>\n\n\n\n<li>suspicions that the doctor has about the presence of developmental abnormalities or diseases in the fetus;<\/li>\n\n\n\n<li>pregnancy resulting from the use of assisted reproductive techniques or surrogacy;<\/li>\n\n\n\n<li>multiple pregnancy;<\/li>\n\n\n\n<li>whether the pregnant woman is at risk of developing hereditary pathologies in the fetus.<\/li>\n<\/ul>\n\n<p>According to the indications of 3D and 4D ultrasound, it can be prescribed at an earlier (13-18 weeks) gestation. Advanced ultrasound capabilities allow:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>see and examine internal organs;<\/li>\n\n\n\n<li>examine the appearance in detail;<\/li>\n\n\n\n<li>measure anatomical parameters (fetal dimensions);<\/li>\n\n\n\n<li>to study the state and functioning of the circulatory system (Doppler mapping of blood vessels).<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Advantages and disadvantages of the extended method<\/h2>\n\n<p>If we compare 3D and 4D ultrasound with a simple two-dimensional ultrasound, we can identify both the advantages and disadvantages of the diagnostic method.<\/p>\n\n<p><strong>The disadvantage is the following:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>longer examination time. In order to obtain the required image of the fetus&#8217; face, it takes time for the fetus to take a certain position in the uterus in relation to the device&#8217;s sensor;<\/li>\n\n\n\n<li>certain limitations that reduce the image quality or do not allow you to see the desired angle of the fetus;<\/li>\n\n\n\n<li>Prolonged exposure to ultrasonic waves can theoretically lead to tissue damage caused by the effect of cavitation (bubble formation) or thermal radiation.<\/li>\n<\/ul>\n\n<p><strong>However, the advantages of the research method significantly outweigh its disadvantages. 3D and 4D ultrasound allow:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>to see in more detail the diagnostic findings revealed as a result of a 2-dimensional ultrasound;<\/li>\n\n\n\n<li>to clarify some anatomical markers of chromosomal pathologies;<\/li>\n\n\n\n<li>measure the thickness of the collar zone;<\/li>\n\n\n\n<li>avoid false-positive or false-negative results of other tests for Down syndrome;<\/li>\n\n\n\n<li>to identify pathologies of the facial area of the skull (&#8220;hare lip&#8221;, abnormalities of the nose and eyes);<\/li>\n\n\n\n<li>to detect abnormalities in the development of the fetal neural tube at an early stage, since three-dimensional imaging and spatial reconstruction provide much more information than two-dimensional imaging;<\/li>\n\n\n\n<li>allows you to see and evaluate the behavioral reactions of the fetus, which can be used to assess the possibility of pathologies of internal organs;<\/li>\n\n\n\n<li>the ability to clarify the diagnosis by tracking the functioning of organs, such as the heart or blood transport in blood vessels.<\/li>\n<\/ul>\n","protected":false},"template":"","kategoriia-vagitnist-prenatalna":[546],"class_list":["post-33326","vagitnist","type-vagitnist","status-publish","hentry","kategoriia-vagitnist-prenatalna-pregnancy-management"],"_links":{"self":[{"href":"https:\/\/ivmed.ua\/en\/wp-json\/wp\/v2\/vagitnist\/33326","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ivmed.ua\/en\/wp-json\/wp\/v2\/vagitnist"}],"about":[{"href":"https:\/\/ivmed.ua\/en\/wp-json\/wp\/v2\/types\/vagitnist"}],"wp:attachment":[{"href":"https:\/\/ivmed.ua\/en\/wp-json\/wp\/v2\/media?parent=33326"}],"wp:term":[{"taxonomy":"kategoriia-vagitnist-prenatalna","embeddable":true,"href":"https:\/\/ivmed.ua\/en\/wp-json\/wp\/v2\/kategoriia-vagitnist-prenatalna?post=33326"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
