White matter lesions

Causes. White matter hyperintensities can be caused by a variety of factors including ischemia, micro-hemorrhages, gliosis, damage to small blood vessel walls, breaches of the barrier between the cerebrospinal fluid and the brain, or loss and deformation of the myelin sheath. If the nervous system were a computer network, gray matter – a non-myelinated portion that contains nerve cells and capillaries – would be the computers and white matter the cables. Although diseased white matter impairs the nervous system much like broken, frayed or poorly operating cables impair a computer network, research was mostly focused on gray matter until Charles DeCarli came along. DIR has been used in conjunction with T1-weighted 3-D imaging and PSIR techniques. 1 In a cohort of 16 patients with MS, images acquired using a 3T imager showed that PSIR improves upon White and Grey Matter contrast and increases delineation of shape, size, and boundary between lesions and surrounding GM. 4 Combining it with DIR resulted in a 337% increase in the total number of lesions The general definition of a lesion is an area of atypical tissue, according to the National Cancer Institute. Lesions can be either cancerous (malignant) or benign, meaning not cancerous.

Occasionally, the finding is incidental, and the patient is apparently asymptomatic. Current methods for grading white matter lesions rely on little more than the "trained eye," researchers say, using an imprecise three-point scale, with a score of 1 meaning minimal white spots Although many white matter lesions are nonspecific in nature, the pattern suggestive of MS includes lesions that are periependymal, abutting the ependymal surface, as well as lesions involving the posterior fossa structures, other than for the central pons.

2016-03-25 2021-02-02 2021-02-14 White matter diseases are a group of conditions that predominantly or significantly affect the white matter of the brain. They comprise a vast heterogeneous group and have a variety of appearances and presentations. They cause disease by altering the process of normal myelination. Nevertheless, consideration of the disorders in which white matter is significantly affected serves to highlight both the frequency with which white matter lesions are encountered and the tendency of these lesions to produce patterns of neurobehavioral dysfunction similar to gray matter lesions. White matter disorders can be classified as 2021-02-06 Fazekas scale for white matter lesions Dr Mostafa El-Feky ◉ and Assoc Prof Frank Gaillard ◉ ◈ et al. The Fazekas scale is used to simply quantify the amount of white matter T2 hyperintense lesions usually attributed to chronic small vessel ischemia, although clearly not all such lesions are due to this.

1 The situation is particularly vexing if the patient White matter lesions are normally discrete, not nearby blood vessels, and sometimes have MRI characteristics that help us know they are due to a stroke or MS. It is possible that one looks like the other, depending on what kind of MRI is done, and who is interpreting it.

I’ve worked with medical imaging centers for a number of years so am always interested in learning about specific cases as well as advancements in the imaging field. However, some findings such as sparing the infratentorial white matter, the restricted diffusion, and the prominent involvement of the pallidum are unusual for ADEM.

One of the most common questions in daily radiology practice when we see an image like the one Aug 4, 2020 Brain MRI at age 6 years showed symmetrical, diffuse deep white matter lesions with sparing of the subcortical areas and U-fibers (Fig.1a). At the T2-weighted imaging shows multiple lesions throughout the white matter (A) that are also clearly visible on inversion recovery imaging (B).
