A hyperintensity or T2 hyperintensity is an area of high intensity ... For example, deep white matter hyperintensities are 2.5 to 3 times more likely to occur in ...
FLAIR hyperintensity confined to sulcus and/or cortex/subcortical white matter in one location < 5 cm FLAIR hyperintensity 5 to 10 cm, or more than 1 site of involvement, each measuring < 10 cm FLAIR hyperintensity measuring > 10 cm, often with significant subcortical white matter and/or sulcal involvement.
T 2 *-weighted sequences are used to detect deoxygenated hemoglobin, methemoglobin, or hemosiderin in lesions and tissues. [2] Diseases with such patterns include intracranial hemorrhage, arteriovenous malformation, cavernoma, hemorrhage in a tumor, punctate hemorrhages in diffuse axonal injury, superficial siderosis, thrombosed aneurysm, phleboliths in vascular lesions, and some forms of ...
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.
A higher VO2 max helps your body use oxygen more efficiently, meaning you can sustain effort longer without feeling exhausted, says Sims. Better strength training endurance: ...
White matter is composed of bundles, which connect various grey matter areas (the locations of nerve cell bodies) of the brain to each other, and carry nerve impulses between neurons.
The study primarily examined examples of narcissism in the workplace, but Durvasula said dealing with a narcissist in a family or friend circle is often more challenging due to the deeper ...
For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions, such as multiple sclerosis (MS) plaques. [1] It was invented by Graeme Bydder, Joseph Hajnal, and Ian Young in the early 1990s. [2]
