Ct.ThAT and Ct.PoAT were obtained at the tibia in 15 patients from a 2-D transverse isotropic free plate model fitted to measured guided wave dispersion curves. The  velocities of the first arriving signal (upsilonFAS) and A0 mode (upsilonA0) were also determined. Site-matched peripheral quantitative computed tomography (pQCT)  provided volumetric cortical bone mineral density (Ct.vBMDpQCT) and Ct.ThpQCT. Good agreement was found between Ct.ThAT and Ct.ThpQCT (R(2)=0.62, root mean square error [RMSE]=0.39 mm). Ct.vBMDpQCT correlated with Ct.PoAT (R(2)=0.57), upsilonFAS (R(2)=0.43) and upsilonA0 (R(2)=0.28). Furthermore, a significant correlation was found between AT and distal high-resolution pQCT. The measurement of cortical parameters at the tibia using guided waves might improve the prediction of bone fractures in a cost-effective and radiation-free manner.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The aim of this study was to estimate cortical porosity (Ct.Po) and cortical thickness (Ct.Th) using 500-kHz bi-directional axial transmission<\/p>\n","protected":false},"author":22,"parent":0,"menu_order":0,"template":"","format":"standard","meta":{"_acf_changed":false},"tags":[],"thema":[5866,5920],"produktgruppe":[5825],"literatur_kategorie":[7223],"class_list":["post-165864","literatur","type-literatur","status-publish","format-standard","hentry","thema-diagnostics-using-leonardo-pqct","thema-pre-clinical-research","produktgruppe-pqct-en","literatur_kategorie-pre-clinical-studies"],"acf":[],"_links":{"self":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur\/165864","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur"}],"about":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/types\/literatur"}],"author":[{"embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/users\/22"}],"version-history":[{"count":0,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur\/165864\/revisions"}],"wp:attachment":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/media?parent=165864"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/tags?post=165864"},{"taxonomy":"thema","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/thema?post=165864"},{"taxonomy":"produktgruppe","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/produktgruppe?post=165864"},{"taxonomy":"literatur_kategorie","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur_kategorie?post=165864"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
