Panels (A) and (B) show the results of wall motion (systolic wall thickening as a percentage of diastolic thickness) and myocardial signal intensity from the cine FPP images in the 4 ischemic dogs. For (A), consecutive frames from peak LV enhancement and for (B) a diastolic frame during myocardial enhancement phase were analyzed. Panel (C) compares the ischemic-to-remote myocardial image contrast (for the 4 ischemic dogs) of the cine FPP images to standard FPP (SR-prepared ECG-gated FLASH), which shows that cine FPP has slightly higher CNR (3.6 vs. 3.3; statistically insignificant). Finally, (D) compares the detected deficit area (in mm2) between cine and standard FPP in all 5 studied dogs (1 with no occlusion), which shows a very good correlation (r=0.99).
