Because it does not have MR or CT capabilities, attenuation correction based on an estimation of the attenuation map is a crucial feature. In this article, we demonstrate this method on [18F]FDG PET brain scans performed with a low-resolution proof of concept prototype of NeuroLF called BPET. We perform an affine registration of a template PET scan to the uncorrected emission image, and then apply the resulting transform to the corresponding template attenuation map. Using a whole-body PET\/CT system as reference, we quantitively show that this method yields comparable image quality (0.893 average correlation to reference scan) to using the reference \u00b5-map as obtained from the CT scan of the imaged patient (0.908 average correlation). We conclude from this initial study that attenuation correction using template registration instead of a patient CT delivers similar results and is an option for patients undergoing brain PET.<\/p>\n<p>&nbsp;<\/p>\n\t\t\t\t\t\t\t\n\t\t\t\t\t<\/div> \n\t\t\t\t\t\n\t\t\t\t\t <div class=\"txt-textfield-btns pt-2 text-left\">\n\t\t\t\t\t\t   \n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"btn  btn-primary \" href=\"https:\/\/www.positrigo.com\/wp-content\/uploads\/2022\/12\/Jehl-et-al.-2022.pdf\" target=\"_self\">Read publication<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"btn  btn-primary \" href=\"https:\/\/www.mdpi.com\/2313-433X\/9\/1\/2\" target=\"_self\">Journal Website<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t \n\t\t\t\t\t<\/div> \n\t\t\t\t\n\t\t\t\t\t\t\n\t\n\t\t\t\t<\/div>\n\n\t\t \n\t\t\t\n\t\t\t\n\t\t\t\n\n\t\t\t\t\t\n\t\t <\/div> \t\n\t\t<\/div>\n\t \n\t  \n \n \n\t<\/div>\n<\/section>\n\n","protected":false},"excerpt":{"rendered":"<p>December 21, 2022<br \/>\nPositrigo team co-authors proof-of-concept study<\/p>\n","protected":false},"author":4,"featured_media":7258,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"content-type":"","footnotes":""},"categories":[18],"tags":[],"class_list":["post-7428","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"_links":{"self":[{"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/posts\/7428","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/comments?post=7428"}],"version-history":[{"count":0,"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/posts\/7428\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/media\/7258"}],"wp:attachment":[{"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/media?parent=7428"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/categories?post=7428"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.positrigo.com\/en-gb\/wp-json\/wp\/v2\/tags?post=7428"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
