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.
CT scan may show hyperdense intra-axial hemorrhage in the subcortical region. Diffuse white matter hypodensities in both cerebral hemispheres may represents microangiopathic changes. On MRI these lesions will be presented as blooming artifact on gradient echo and susceptibility weighted imaging. [3]
Neuroimaging techniques such as Computed Tomography (CT) scan or Magnetic Resonance imaging (MRI) are typically used to detect the presence of degenerative subcortical white matter. [26] Microscopy of the cerebrospinal fluid can also be used for diagnosis, where swollen astrocytes with distorted and elongated mitochondria can be seen in ...
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]
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.
Evidence from subcortical small infarcts suggests that motor fibers are somatotopically arranged in the human corona radiata. Following subtotal brain damage, localization of the corticofugal projection in the corona radiata and internal capsule can assist in evaluating a patient's residual motor capacity and predicting their potential for functional restitution.
Radiology, neurology Amyloid-related imaging abnormalities ( ARIA ) are abnormal differences seen in magnetic resonance imaging of the brain in patients with Alzheimer's disease . ARIA is associated with anti-amyloid drugs , particularly human monoclonal antibodies such as aducanumab . [ 1 ]
They do not spread into the subcortical white matter and never show gadolinium enhancement. Over a one-year period, CLs can increase their number and size in a relevant proportion of MS patients, without spreading into the subcortical white matter or showing inflammatory features similar to those of white matter lesions.
