Figure 2. Effects of change in image contrast on BSI calculations.

Figure 2

(a) The top row, going from left to right, are the images of the 5 degree flip angle, 12 degree flip angle and fast spin echo SPGR scan. (b) Below each scan mentioned above is its BSI object map overlaid on the base SPGR scan. In each case the BSI object map pictorially illustrates those pixels where volume difference was measured between the base and the second altered scan in the pair. The red and green pixels represent a color map of BSI computed change in volume superimposed on the baseline grey scale MRI scan. Red indicates shrinkage and green expansion of the color annotated pixel
