FIG 1. A, T2 and contrast enhancing contours overlaid on a GRE EPI and corresponding resampled T2* signal intensity time curves. B, Plot of T2* signal intensity time curve, S(t), for one voxel with red solid arrow denoting the time of contrast agent injection. C, Relative concentration curve obtained. Peak height is the distance from 1 to 2, while percent recovery represents how much the post-bolus signal (3) has recovered from the peak (2).
