We used 7 T MRI to compare dentate granule cell layer (DGCL) morphology in schizophrenic patients to matched controls. Three blinded neuroradiologists rated each DGCL on a qualitative scale of 1 to 6 (from not discernable to easily visible, appearing dark gray or black). MRI identification of the DGCL was validated with histopathology. Mean right and left DGCL ratings were 3.21.0 and 3.51.2 in patients versus 3.91.1 and 3.80.8 in controls. The right DGCL was less discernible in schizophrenia patients compared to controls (p0.05), presumably reflecting morphological abnormalities due to cellular organization.
