Mean Values of Patients With Chronic Schizophrenia and Normal Comparison Subjects for Measures of Fractional Anisotropya in the Uncinate Fasciculus, Reflecting White Matter Integrity
a Deviation from the isotropic diffusion.
b Significant group-by-side interaction (ANOVA, p≤0.05) and significant asymmetry in the comparison subjects (t test, p<0.05).

Diffusion Tensor Map for a Selected Coronal Plane in a Normal Comparison Subject, Showing the Directionality of the White Matter Tractsa
a The blue lines indicate the in-plane diffusion, and the other colors indicate the magnitude of the out-of-plane diffusion, with red-orange indicating the maximal diffusion. Note the clear appearance of the uncinate fasciculi (orange-red) bilaterally within the temporal stem (see arrows).

Approximate Location of the Brain Slice Selected for Measurement of Anisotropic Water Diffusion in the Uncinate Fasciculus in Patients With Chronic Schizophreniaa
a The posterior line intersects the uncinate fasciculus in the densest portion, perpendicular to the plane (thus it was selected for the measurements), whereas the anterior line intersects the fewest number of fibers perpendicular to the plane. Adapted from Gray’s Anatomy of the Human Body as displayed at Bartleby.com (36).

Conventional T2-Weighted Image, Fractional Anisotropya Map, and Out-of-Plane Diffusion Map for a Selected Coronal Plane in a Normal Comparison Subjectb
a Deviation from the isotropic diffusion.
bThe conventional image does not show white matter fiber tracts in the brain. The fractional anisotropy map highlights the white matter bundles in the brain, with the red arrows pointing to the uncinate fasciculi. The image on the right displays the out-of-plane component of the diffusion; high intensity corresponds to the fiber tracts perpendicular to the plane, thus differentiating the uncinate fasciculi from the fiber tracts with other directions (again, red arrows point to uncinate fasciculi).
