Figure 4.
Edema-weighted (T2-STIR) and late gadolinium enhancement (LGE) images from the same animal as in Figure 3, obtained within 20 minutes of ischemia induction and 3-hours post reperfusion, and TTC image confirming the infarct territory are shown. No edema (absence of elevation in T2-weighted signal) or infarction was observed within the 20 minutes of ischemia induction (left); post reperfusion (preceded by 3-hr ischemia), both edema and infarction were readily apparent in regions where Systolic to Diastolic ratio (S/D) changes were observed during the early ischemic phase (Figure 3).
