WebDec 3, 2024 · Flair hyperintensity often refers to a bright spot on a sequence called FLAIR in the brain. This can be from many causes but is commonly seen from chronic microvascular disease. Other causes can be demyelination, strokes, bleeds and tumors. The other sequences and appearance will help narrowdown the possibilities. White matter … WebMar 30, 2010 · How often have you read, “There are small scattered foci of signal abnormalities (T2 hyperintensities or increased FLAIR signal) in the cerebral white matter indicative of demyelinating disease, chronic white matter ischemia due to microvascular disease, or gliosis from an infectious/inflammatory disease process,” or words just like …

WebFeb 10, 2024 · In this context, it is vital to not miss a focal parenchymal abnormality characterised by T2 hyperintensity (with/without focal restricted diffusion), mass effect, perilesional vasogenic oedema and/or enhancement which indicates the true causative pathology of the seizure [ 12 ]. Metabolic causes: hypoglycaemia WebLeukoaraiosis 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.

WebThe fluid-attenuated inversion recovery (FLAIR) pulse sequence cancels the signal intensity from CSF and causes heavy T2 weighting because of the very long TE, resulting in excellent definition of anatomic detail, such as brain surface sulci, and high lesion contrast in areas close to the CSF. 12 This method is commonly used to detect meningeal ...
