Quantification of local helical angle (HA) at three levels from base to apex of the rat heart (a) before, (b) 9 h after and (c) 342 h after ethanol immersion. Difference in local HA between the heart before and 9 h after (d) and 342 h after (e) ethanol immersion. The average HA difference () was calculated for each image slice. |
