    CT image showing extensive low attenuation in the right hemispheric white matter due to dilated Type 2 perivascular spaces Axial fat-suppressed T2-weighted MRI image in the same patient as above demonstrating extensive dilated Type 2 perivascular spaces in the right hemisphere Perivascular space is depicted in the inset box.

  3. Binswanger's disease - Wikipedia

    en.wikipedia.org/wiki/Binswanger's_disease

    Binswanger's disease, also known as subcortical leukoencephalopathy and subcortical arteriosclerotic encephalopathy, [1] is a form of small-vessel vascular dementia caused by damage to the white brain matter. [2] White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age. [3]

  4. Megalencephalic leukoencephalopathy with subcortical cysts

    en.wikipedia.org/wiki/Megalencephalic...

    Seizures and delays in motor development are also prevalent. Additionally, mild mental retardation can be observed. Patients often exhibit diffuse swelling of the cerebral white matter and large subcortical cysts in the frontal and temporal lobes, with cysts developing on the tips of the temporal and subcortical areas.

  5. Claustrum - Wikipedia

    en.wikipedia.org/wiki/Claustrum

    It contains the highest density of connecting white matter tracts in the cortex. This supports the notion of networking and coordination among different regions of the brain. [ 12 ] The claustrum has regional specificity to it; information coming in from visual centers project to specific areas of grey matter neurons in the structure and the ...

  6. Leukoencephalopathy - Wikipedia

    en.wikipedia.org/wiki/Leukoencephalopathy

    Leukoencephalopathy (leukodystrophy-like diseases) is a term that describes all of the brain white matter diseases, whether their molecular cause is known or unknown. [1] It can refer specifically to any of these diseases: Progressive multifocal leukoencephalopathy; Toxic leukoencephalopathy

  7. Intracranial hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intracranial_hemorrhage

    Those with parenchymal contusion would require frequent follow-up imaging because such contusions may grow large enough to become hemorrhage and exerts significant mass effect on the brain. [3] Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are ...

  8. Diffusion-weighted magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Diffusion-weighted...

    Diffusion tensor imaging (DTI) is important when a tissue—such as the neural axons of white matter in the brain or muscle fibers in the heart—has an internal fibrous structure analogous to the anisotropy of some crystals. Water will then diffuse more rapidly in the direction aligned with the internal structure (axial diffusion), and more ...

  9. Hyperintensity - Wikipedia

    en.wikipedia.org/wiki/Hyperintensity

    These small regions of high intensity are observed on T2 weighted MRI images (typically created using 3D FLAIR) within cerebral white matter (white matter lesions, white matter hyperintensities or WMH) [1] [2] or subcortical gray matter (gray matter hyperintensities or GMH). The volume and frequency is strongly associated with increasing age. [2]
