Over time, the MRI is excellent at showing rarefaction and cystic degeneration of the white matter as it is replaced by fluid. To show this change, displaying white matter as a high signal (T2-weighted), proton density, and Fluid attenuated inversion recovery (FLAIR) images are the best approach. T2-weighted images also displaying cerebrospinal ...
The degeneration of white matter can be seen in an MRI scan and is used to diagnose leukodystrophy. Leukodystrophy is characterized by specific symptoms, including decreased motor function, muscle rigidity, and eventual degeneration of sight and hearing. While the disease is fatal, the age of onset is a key factor, as infants have a typical ...
Leukoencephalopathy with neuroaxonal spheroids (LENAS) is believed to occur when presence of white matter degeneration and axonal spheroids are seen with a brain biopsy or an MRI. [6] [3] White matter consists of nerve fibers covered by a substance called myelin that insulates and protects them. [3]
Researchers collected MRI data to evaluate brain white matter health and microstructure, with analysis focusing on white matter volume, ... Diffusion-weighted images underwent processing ...
Brain MRI of a 65-year-old woman with frontotemporal dementia. Cortical and white matter atrophy of the frontal lobes is clear in all images. Specialty: Psychiatry, neurology: Causes: frontotemporal lobar degeneration
PML is diagnosed in a patient with a progressive course of the disease, finding JC virus DNA in spinal fluid together with consistent white-matter lesions on brain magnetic resonance imaging (MRI); alternatively, a brain biopsy is diagnostic [1] when the typical histopathology of demyelination, bizarre astrocytes, and enlarged oligodendroglial ...
Head CT showing periventricular white matter lesions. Leukoaraiosis is a particular abnormal change in appearance of white matter near the lateral ventricles. It is often seen in aged individuals, but sometimes in young adults. [1] [2] On MRI, leukoaraiosis changes appear as white matter hyperintensities (WMHs) in T2 FLAIR images.
MRI can aid in the detection of injured brain tissue; however, the severity and extent of the damage demonstrated by imaging does not always reflect patient clinical status. [8] Toxic leukoencephalopathy encompasses the degeneration of white matter tracts devoted to higher cerebral function; [ 2 ] however, white matter can appear normal until ...
