“…The radial glias retract their ventricular and pial attachments and differentiate into astrocytes as the brain matures normally, with corresponding decrease in the cortical FA value. The radially oriented structure within the cortex demonstrated in this case may represent remains of radial glia or persistent radial orientation of neurons arrested in the migration process [7]. …”

“…Previous 3D tractography studies identified these as separate, thick, brush-like fibers. 11,12 However, our case did not demonstrate similar fiber anatomy. We also identified a small fiber bundle across the small posterior interhemispheric fissure dorsal to the fused midline mass.…”

Holoprosencephaly is the most common developmental disorder of the prosencephalon. We present a case of alobar holoprosencephaly with cortical migration anomalies, a large midline mass, a monooptic nerve, and no dorsal cyst. Diffusion tensor tractography showed markedly abnormal supratentorial and posterior fossa white matter fibers, along with an enlarged hippocampal commissure across the dorsal midline cerebrum and a monooptic nerve projecting toward the cerebellum. Fiber tracking revealed information about white matter composition and organization not evident with conventional MR imaging.

Diffusion MRI is an imaging technique that uses the random motion of water to probe tissue microstructure. Diffusion tensor imaging (DTI) can quantitatively depict the organization and connectivity of white matter. Given the non-invasiveness of the technique, DTI has become a widely used tool for researchers and clinicians to examine the white matter of children. This review covers the basics of diffusion-weighted imaging and diffusion tensor imaging and discusses examples of their clinical application in children.

Demonstration of different histological layers of the pachygyria/agyria cortex using diffusion tensor MR imaging

Abstract: DTI is a useful tool for identifying gross histological features of pachygyria-agyria complex. Superficial layer and thickened fourth layer demonstrate high anisotropy. Identification of anisotropy in the superficial layer has not been described in previous reports.
