![]() The brain specimens contained white matter of different organization and localization: brainstem, corpus callosum, frontal and parietal tracts, subcortical white matter. ![]() The ex vivo CP OCT images were collected from autopsy subjects of the human brain. The aim of this study was to visualize white matter organization of eloquent brain areas with CP OCT using post-processing methods. It looks perspective not just to detect white matter, but also receive information about its condition – the myelination rate and presence of ordered fibers. Crosspolarization (CP) OCT is a so-called functional extension of OCT that seems to have benefits in visualization of myelin. Since gliomas often tend to grow close to eloquent brain areas, the question of the proximity of the tumor to white matter tracts sharply arise during tumor resection to prevent their damage. Optical coherence tomography (OCT) is a promising method for clarifying the boundaries of the infiltrative brain tumors within surrounding white matter.
