What is foci white matter?
White-matter foci not adjacent to the lateral ventricles were found to be related to performance on immediate visual memory/visuoperceptual skills, visuomotor tracking/psychomotor speed and, to a lesser degree, learning capacity and abstract and conceptual reasoning skills.
Are white matter lesions serious?
Serious consequences of periventricular white matter lesions — this is the scary part. There is strong evidence that cerebral white matter lesions impair brain function, and in particular impair thinking ability and walking.
What does few scattered punctate foci mean?
The presence of a few hyperintense punctate foci in the cerebral white matter at MRI is a very common finding that can be regarded as insignificant in most of the cases. These bright dots, considered as normal, can be a manifestation of dilated perivascular spaces or small gliotic or lacunar ischemic foci.
Can stress cause lesions on the brain?
Psychological stress is linked to multiple sclerosis (MS) severity (e.g., to a heightened risk of brain lesion development).
Does white matter lesions mean MS?
DIFFERENTIAL RADIOLOGICAL DIAGNOSIS OF WHITE MATTER LESIONS. White matter T2 hyperintensities in the brain are not specific to MS and are seen in a number of other disorders. They can even be seen in otherwise normal individuals, particularly with increasing age.
What are punctate lesions?
Background: Punctate white matter lesions (PWMLs) are small focal patches of increased signal intensity (SI) on T1- and decreased SI on T2-weighted magnetic resonance imaging (MRI). To date, there have been few reports of PWMLs in term born infants.
What causes T2 Flair hyperintensity?
T2 hyperintensities may occur in demyelinating diseases such as multiple sclerosis, vasculitis (inflammation of the arteries in the brain), lyme disease. It’s important to note that any tissue with a high water or protein content will tend to appear very bright on the T2 sequence.
What are T2 foci?
Background: T2-hyperintense foci are one of the most frequent findings in cerebral magnetic resonance imaging (MRI). They can pose serious diagnostic problems which is reflected by their English name and abbreviation – UBOs (Unidentified Bright Objects).
What is a T2 hyperintense foci?
a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. Usually this is due to an increased water content of the tissue. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up.
What is non specific foci?
what is non specific foci – “Foci” means an area of localized infection or disease. “Non specific” means they don’t know from what, it could be nothing (like an old injury or bruise), or the beginning of some disease process.
