Before Following a radiofrequency pulse, this form of relaxation occurs with the time constant T2, where T2 is the time it takes for the transverse magnetization vector to decay to 1/e or 37% of its initial magnitude. You have brain structures that show up white on MRI in this area. Whether these radiological lesions correspond to irreversible histological changes is still a matter of debate.

White matter hyperintensities (WMHs) are lesions in the brain that show up as areas of increased brightness when visualised by T2-weighted magnetic resonance imaging (MRI). Background: White matter hyperintensities (WMH) lesions on T2/FLAIR brain MRI are frequently seen in healthy elderly people. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). These small regions of high intensity are observed on T2 weighted MRI images (typically created using 3D FLAIR) within cerebral white matter (white matter lesions, white matter hyperintensities or WMH)[1][2] or subcortical gray matter (gray matter hyperintensities or GMH). Long T2 fluids with few macromolecules such as water, urine, and CSF will appear bright on T2-weighted images. For example, deep white matter hyperintensites are 2.5 to 3 times more likely to occur in bipolar disorder and major depressive disorder than control subjects. An estimated 25 percent of people 40 years of age and 50 percent of people 50 years of age have simple kidney cysts. Characterization of the abnormal areas of T2 signal as well as their appearance on other MR imaging sequences, when combined with clinical context and laboratory investigations, will often allow a unique diagnosis, or at least aid in narrowing the differential diagnosis.

These foci were not related to cognitive function or cerebrovascular risk factors; instead, they were highly correlated to age, being present in 11 of 11 subjects aged 75 years and over. An increase in T2 signal intensity is often associated with chronic compression of the spinal cord, and it is well established that chronic compression results in structural changes to the spinal cord. Hyperintensities are commonly divided into 3 types depending on the region of the brain where they are found. 2 How do you treat inflammation of the supraspinatus tendon?
