Figure 1

(A) Representative set of T2* (color-coded) and T2 maps, T2-STIR and LE images acquired from a canine on day 5 post reperfusion are shown. Arrows point to the site of infarction on LE image. Hemorrhagic territory (Hemo+) is enclosed in blue ROI, and remote territory is enclosed in red ROI. (B) Mean T2* of Hemo+ was significantly lower than those of Remote and Hemo- (#, p<0.001). Mean T2 of both Hemo+ and Hemo- were elevated compared to Remote (* and ^, p<0.001), with T2 of Hemo- higher than that of Hemo+ (p<0.001). (C) Compared to remote, T2* of Hemo+ decreased by 39% (p<0.001), while T2* of Hemo- remained unchanged (p=0.21). T2 of Hemo- and Hemo+ remained elevated by 26% and 17% respectively (p<0.001 for both cases). STIR-SI of Hemo- and Hemo+ were also elevated by 59% and 31% respectively (p<0.001 for both cases).
