Table 2.
An example of p-value tables used to determine the significance of a comparison for different STU for FA data in six different ROI. The ROI are internal capsule (IC), frontal white matter (FW), centrum semiovale (CS), globus pallidus (GP), putamen (Put), and the splenium of the corpus callosum (SCC). This comparison is between scans on the same GE 3.0T scanner at two different TE values. Significant differences (p <0.05) are shaded in grey. The number of STU is on the horizontal axis and the ROI identity is represented on the vertical axis.
