The findings demonstrate a strong association and agreement between 4DMedical\u2019s CT LVAS and PET-ventilation at the lobar level and comparable correlation at the voxel level. Utilizing routine non-contrast CT scans, CT LVAS generates detailed regional ventilation information. This highlights CT LVAS as a safe and contrast-free modality for functional lung imaging, making it an ideal tool for assessing lung function across a range of respiratory conditions.","breadcrumb":{"@id":"https:\/\/4dmedical.com\/us\/blog\/2025\/09\/04\/4dmedicals-ctvq-receives-fda-510k-clearance-first-and-only-non-contrast-vq-imaging\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/4dmedical.com\/us\/blog\/2025\/09\/04\/4dmedicals-ctvq-receives-fda-510k-clearance-first-and-only-non-contrast-vq-imaging\/"]}]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/4dmedical.com\/us\/blog\/2025\/09\/04\/4dmedicals-ctvq-receives-fda-510k-clearance-first-and-only-non-contrast-vq-imaging\/#primaryimage","url":"https:\/\/4dmedical.com\/us\/wp-content\/uploads\/sites\/2\/2025\/09\/CTVQ-Banner-Image-1920x1080-2.jpg","contentUrl":"https:\/\/4dmedical.com\/us\/wp-content\/uploads\/sites\/2\/2025\/09\/CTVQ-Banner-Image-1920x1080-2.jpg","width":1920,"height":1080,"caption":"CT:VQ\u2122 Non-Contrast Lung Ventilation Perfusion"},{"@type":"BreadcrumbList","@id":"https:\/\/4dmedical.com\/us\/blog\/2025\/09\/04\/4dmedicals-ctvq-receives-fda-510k-clearance-first-and-only-non-contrast-vq-imaging\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/4dmedical.com\/us\/"},{"@type":"ListItem","position":2,"name":"4DMedical&#8217;s CT:VQ\u2122 Receives FDA 510(k) Clearance; First-and-Only Non-Contrast VQ Imaging"}]},{"@type":"WebSite","@id":"https:\/\/4dmedical.com\/us\/#website","url":"https:\/\/4dmedical.com\/us\/","name":"4DMedical US","description":"","publisher":{"@id":"https:\/\/4dmedical.com\/us\/#organization"},"potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/4dmedical.com\/us\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"en-US"},{"@type":"Organization","@id":"https:\/\/4dmedical.com\/us\/#organization","name":"4DMedical US","url":"https:\/\/4dmedical.com\/us\/","logo":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/4dmedical.com\/us\/#\/schema\/logo\/image\/","url":"https:\/\/4dmedical.com\/us\/wp-content\/uploads\/sites\/2\/2022\/09\/4D-logo-on-navy.png","contentUrl":"https:\/\/4dmedical.com\/us\/wp-content\/uploads\/sites\/2\/2022\/09\/4D-logo-on-navy.png","width":418,"height":83,"caption":"4DMedical US"},"image":{"@id":"https:\/\/4dmedical.com\/us\/#\/schema\/logo\/image\/"}},{"@type":"Person","@id":"https:\/\/4dmedical.com\/us\/#\/schema\/person\/dac6f29cd556fa750bdea707a0899844","name":"Michelle Martin","image":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/secure.gravatar.com\/avatar\/5f8f4ffe4d9ac18164566998f6d39caa95d4747465a8dac4072582d7c282399f?s=96&d=mm&r=g","url":"https:\/\/secure.gravatar.com\/avatar\/5f8f4ffe4d9ac18164566998f6d39caa95d4747465a8dac4072582d7c282399f?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/5f8f4ffe4d9ac18164566998f6d39caa95d4747465a8dac4072582d7c282399f?s=96&d=mm&r=g","caption":"Michelle Martin"},"url":"https:\/\/4dmedical.com\/us\/blog\/author\/mmartin4dmedical-com\/"}]}},"_links":{"self":[{"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/posts\/48262","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/comments?post=48262"}],"version-history":[{"count":3,"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/posts\/48262\/revisions"}],"predecessor-version":[{"id":48269,"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/posts\/48262\/revisions\/48269"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/media\/48267"}],"wp:attachment":[{"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/media?parent=48262"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/categories?post=48262"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/4dmedical.com\/us\/wp-json\/wp\/v2\/tags?post=48262"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
