FIGURE 7. Results of the canine studies (n=3).

FIGURE 7

LGE images (top row) are used as the reference to evaluate whether the corresponding resting FPP images (bottom row) acquired using the proposed method can detect perfusion defects corresponding to the subendocardial infarcts. All perfusion images correspond to the peak myocardial enhancement phase. (a1,b1): Result of the control animal study with no perfusion defects, which is consistent with the negative LGE. (a2,b2): Result of the chronic MI study with a small subendocardial infarct (red arrow in a2). The perfusion defect (≈3 mm width) is clearly seen in (b2) demonstrating the ability of the proposed method to resolve small subendocardial defects. (a3,b3): Result of the acute MI study, which shows subendocardial perfusion defect in the all LGE-positive segments. Among the 3 studies, only minimal DRA is seen in (b3) and (b1, b2) are virtually free of DRA.
