Its promising results in social, political, economic and even scientific fields give AI a preferential place, for which interest and applications are growing at a dizzying pace.<\/p>\n<p>This context is the ideal framework for the study, &#8216;Artificial intelligence (AI) based triage for preimplantation genetic testing (PGT); an AI model that detects novel features in the embryo associated with ploidy&#8217;, presented at the <a href=\"https:\/\/www.eshre.eu\/ESHRE2022\">38th edition of the Congress of the European Society of Human Reproduction and Embryology<\/a> (ESHRE) led by <a href=\"https:\/\/www.ivi-rmainnovation.com\/investigators\/marcos-meseguer\/\">Dr. Marcos Meseguer<\/a>, embryologist and scientific supervisor of <a href=\"https:\/\/ivi.es\/clinicas\/valencia\/\">IVI Valencia<\/a>.<\/p>\n<p>\u201cThis is a pioneering study, since, for the first time in the world, we have developed and combined five independent modules that analyse embryo characteristics using computer vision, thus achieving an accuracy of 90% in the prediction of chromosomally normal embryos. Being able to evaluate embryo implantation potential in this way allows us to improve the efficiency of a fundamental process in assisted reproduction, embryo culture and embryo selection\u201d, explained Dr. Meseguer.<\/p>\n<p>This percentage of accuracy is unprecedented, coming close to that obtained by <a href=\"https:\/\/www.ivi.uk\/assisted-reproduction-treatments\/ivf-genetic-screening\/\">invasive genetic testing<\/a> necessitating embryo biopsy. AI offers the possibility of studying the embryo through complex algorithms that circumvent the need to extract cells through manipulation, thus being able to successfully select viable embryos for transfer during <a href=\"https:\/\/www.ivi.uk\/assisted-reproduction-treatments\/in-vitro-fertilisation\/\">IVF treatment<\/a>.<\/p>\n<p>\u201cThe germ of this study responds to an unquestionable reality: embryonic development does not occur in the same way in euploid \u2013 chromosomally normal \u2013 embryos and aneuploid \u2013 chromosomally abnormal \u2013 embryos. At this point, could AI predict ploidy? The five modules that we have been able to analyse and combine show us that yes, it would be possible and reliable\u201d, added Dr. Meseguer.<\/p>\n<p>The study analysed 2,500 embryos \u2013 the most extensive scientific case study in the world \u2013 resulting in a revolutionary technique in the field of embryology, which is non-invasive, universal, standardised, automatic and would improve all current methods of embryo selection.<\/p>\n<p>The five modules studied are:<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_68_1 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title \" >Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.ivi.uk\/blog\/ai-embryo-selection\/#1_Morphokinetic_parameters\" title=\"1) Morphokinetic parameters\">1) Morphokinetic parameters<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.ivi.uk\/blog\/ai-embryo-selection\/#2_Embryo_morphology\" title=\"2) Embryo morphology\">2) Embryo morphology<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.ivi.uk\/blog\/ai-embryo-selection\/#3_Cell_activity\" title=\"3) Cell activity\">3) Cell activity<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.ivi.uk\/blog\/ai-embryo-selection\/#4_Mitochondrial_activity\" title=\"4) Mitochondrial activity\">4) Mitochondrial activity<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.ivi.uk\/blog\/ai-embryo-selection\/#5_Warpingshrinkage\" title=\"5) Warping\/shrinkage\">5) Warping\/shrinkage<\/a><\/li><\/ul><\/nav><\/div>\n<h3><span class=\"ez-toc-section\" id=\"1_Morphokinetic_parameters\"><\/span>1) Morphokinetic parameters<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This module refers to the times at which the most important events of embryonic development occur, i.e. when the embryo divides and accumulates multiple cells until it reaches the blastocyst stage. \u201cBy simply analysing these parameters in the 2,500 embryos studied, we have been able to verify that, taking an euploid embryo as a reference, if another embryo arrives later at an event, its probability of being aneuploid increases considerably\u201d, explains Dr. Meseguer.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Embryo_morphology\"><\/span><strong>2) Embryo morphology<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>An automated analysis of this parameter shows that embryos with good morphology are more likely to be chromosomally normal. The morphology itself has a predictive capacity of 68% for aneuploidy.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Cell_activity\"><\/span><strong>3) Cell activity<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This module consists of measuring the diameter of a cell and the summation of all diameters of all cells of an embryo at a specific moment in its development (normally between 2 to 8 cells). \u201cThis automatically calculates values that are then analysed for 160 images, resulting in chromosomally abnormal or aneuploid embryos with a longer diameter length. This is because they take longer to split, the splitting produces many movements and thus increases the measurement\u201d, adds Dr. Meseguer.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Mitochondrial_activity\"><\/span><strong>4) Mitochondrial activity<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This involves associating the smallest analysable size as regards the image, which is a pixel, with the size of a mitochondrion. Subsequently, the embryo\u2019s pixels are quantified and the changes in quantity and distribution are analysed, comparing them between euploid and aneuploid embryos. Aneuploid embryos have a different number of pixels than euploid embryos, so this module helps predict aneuploidy with 77% accuracy.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Warpingshrinkage\"><\/span><strong>5) Warping\/shrinkage<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Shrinkage occurs in approximately 20% of embryos. After analysing this event using an automated examination, it is observed to occur more frequently in aneuploid embryos.<\/p>\n<p>\u201cIn short, computer vision allows us to emulate our eyes\u2019 capabilities on computers. In other words, it aims to acquire, process, analyse and understand images of the real world in order to produce numerical or symbolic information that can be processed by a computer. And this ultimately allows us to check that embryos behave differently during their development according to their chromosomal content and thus optimise the process of embryo study and the selection of normal and viable embryos for transfer\u201d, concluded Dr. Meseguer.<\/p>\n<p>As a result, the combination of these five modules together with a complex algorithm developed by IVI Valencia in collaboration with the Israeli company AiVF would result in an accuracy of 90% in the selection of chromosomally normal embryos. This would have a direct impact on an increase in pregnancy rates, which would provide an objective and reliable prediction using this fast and economical method.<\/p>\n","protected":false},"excerpt":{"rendered":"A pioneering study from IVI combines five modules of embryo image analysis using AI to detect the number of chromosome sets in a cell 2,500 embryos have been analysed, offering a revolutionary technique in the field of embryology, which is non-invasive, universal, standardised, automatic and improves all current methods of embryo selection Within the framework&#8230; <a class=\"view-article\" href=\"https:\/\/www.ivi.uk\/blog\/ai-embryo-selection\/\">View Article<\/a>","protected":false},"author":42,"featured_media":102767,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[52],"tags":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.5 -
