Figure 3. Anisotropy of primary (PVE1) and secondary (PVE2) fibers for cocaine-use disorder (CUD) and gambling disorder (GD) patients with and without lifetime alcohol-use disorders (AUDs).

Figure 3 shows individual partial volume estimates for primary fibers (PVE1; left) and secondary fibers (PVE2; right) within the corpus genu. No differences in anisotropy were found among CUD patients with and without lifetime AUDs. Primary fiber PVEs were decreased and secondary fiber PVEs were increased among GD patients with a history of AUDs in comparison to those without.

AUD+ = lifetime alcohol-use-disorder; AUD− = no lifetime alcohol-use-disorder; n.s.=not significant; **p≤.01; *p<.05
