In another study, routine clinical brain scans at 3.0 TESLA should a similar appearance as 1.5 TESLA, but with superior image quality and\/or increased speed.<\/p>\n\n\n\n<p>The high&nbsp; field MRI has been reported to determine the extent of identifiable TBI findings in patients suffering from TBI ranging from hippocampal atrophy to dilated perivascular spaces.<\/p>\n","protected":false},"featured_media":1960,"template":"","meta":{"_acf_changed":false,"_seopress_robots_primary_cat":"","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_analysis_target_kw":""},"categories":[77],"class_list":["post-1958","sub-practice-areas","type-sub-practice-areas","status-publish","has-post-thumbnail","hentry","category-neuroimaging"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.cochranfirm.com\/new-orleans\/wp-json\/wp\/v2\/sub-practice-areas\/1958","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.cochranfirm.com\/new-orleans\/wp-json\/wp\/v2\/sub-practice-areas"}],"about":[{"href":"https:\/\/www.cochranfirm.com\/new-orleans\/wp-json\/wp\/v2\/types\/sub-practice-areas"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.cochranfirm.com\/new-orleans\/wp-json\/wp\/v2\/media\/1960"}],"wp:attachment":[{"href":"https:\/\/www.cochranfirm.com\/new-orleans\/wp-json\/wp\/v2\/media?parent=1958"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cochranfirm.com\/new-orleans\/wp-json\/wp\/v2\/categories?post=1958"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
