Figure 7 Slice-by-slice myocardial signal density divided by the left ventricular blood pool signal density (y-axis) versus slice-by-slice microsphere-derived myocardial blood flow (x-axis) in both the stenosed left anterior descending artery territory and remote myocardial territory over the range of flows studied (y = –0.00041x2 + 0.01575x + 0.1937 LR chi-square [2 degrees of freedom] = 14.1, p = 0.001) (n = 163). SD ratio = myocardial signal density/left ventricular blood pool signal density.
