Segmental Tissue Displacement in RT and Sham-Treated Rats
Segmental tissue displacement in RT and sham-treated rats demonstrate maintained tissue motion post-RT. Segmental distribution of average myocardial tissue displacement (A, rotation angle; B, SAX motion, mm; C, LAX motion, mm) in the left ventricle in sham-treated, 8-week, and 10-week post-RT rats. The left-ventricular 17-segment model is used for presenting values at basal, mid-ventricular, and apical levels. Note different tissue displacement values post-RT compared with the sham-treated rats, which differ based on location of the myocardial segment and type of displacement. Abbreviations as in Figure 4.
