The MP-RAGE sequence is a broadly used T1w imaging method with minimal changes over the last 20+ years.  Some of the limitations of T1w MP-RAGE include a fixed singular contrast, lack of quantitative measures, and sensitivity to head motion.  To address these issues, our lab has developed a novel MPnRAGE method, which acquires inversion-recovery prepared imaging data using a 3D radial imaging sequence.  This technique can obtain high resolution (~1mm isotropic), whole brain images with more than 200 T1w image contrasts in comparable imaging time to fully sampled MP-RAGE.  In addition, MPnRAGE can provide quantitative T1 maps from the same data.  Finally, retrospective motion correction methods have been developed to significantly improve image quality when motion occurs. <\/p>\n<p><span class=\"internal-link\"><span class=\"internal-link\"><span class=\"internal-link\"><br \/><\/span><\/span><\/span><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p><!-- description --> <\/p>\n<p class='lead'>Join us for a presentation by Dr. Andrew Alexander, Director of MRI Imaging, Waisman Lab for Brain Imaging and Behavior, University of Wisconsin.<\/p>\n","protected":false},"author":53245,"featured_media":2591,"template":"","meta":{"_acf_changed":false,"_tribe_events_status":"","_tribe_events_status_reason":"","_tribe_events_is_hybrid":"","_tribe_events_is_virtual":"","_tribe_events_virtual_video_source":"","_tribe_events_virtual_embed_video":"","_tribe_events_virtual_linked_button_text":"","_tribe_events_virtual_linked_button":"","_tribe_events_virtual_show_embed_at":"","_tribe_events_virtual_show_embed_to":[],"_tribe_events_virtual_show_on_event":"","_tribe_events_virtual_show_on_views":"","_tribe_events_virtual_url":"","footnotes":"","_links_to":"","_links_to_target":""},"tags":[17],"tribe_events_cat":[],"class_list":["post-3938","tribe_events","type-tribe_events","status-publish","has-post-thumbnail","hentry","tag-biomedical-research-imaging-center","odd"],"pp_force_visibility":null,"pp_subpost_visibility":null,"pp_inherited_force_visibility":null,"pp_inherited_subpost_visibility":null,"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.8 -
