Note.—Significant elevations (P < .0083, significant results italicized) of the lADC were seen in the VST, RST, and ReST of the GL-PL specimens as compared with PF specimens. Post hoc comparisons of tADC values between fixatives were not performed, as the ANOVA was not significant. No significant differences (P < .0083) were seen in the AI of individual tracts between the GL-PF specimens and the PF specimens (SE = standard error).
