My MRI states: There is a single region of three foci of T2 prolongation within the white matter. 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 them in your Background White matter hyperintensities (WMH) lesions on T2/FLAIR brain MRI are frequently seen in healthy elderly people.

"Nonspecific white matter changes". 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. Diagnosis is based on the appearance of the rotator cuff tendons (grading system) and the presence or absence of signs denoting involvement of the subacromial bursa and subacromialsubdeltoid plane. An abnormal prolongation can be associated with metabolic problem. Another possible cause of these white matter lesions could be Lyme disease.

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. 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. after an RF excitation pulse, there is relaxation of the spins from the transverse plane toward the main longitudinal magnetic vector (B 0) - this is T1 weighting. A hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination and axonal loss. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up. [citation needed], Hyperintensities are often seen in auto immune diseases that have effects on the brain. [6], Postmortem studies combined with MRI suggest that hyperintensities are dilated perivascular spaces, or demyelination caused by reduced local blood flow.

Whether these radiological lesions correspond to irreversible histological changes is still a matter of debate. a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. Resting the shoulder and upper arm is necessary at the first sign of pain from an injury. Singapore Med J. The authors present an algorithmic approach to evaluating intrinsic abnormality of . Alteration in muscle T2, notably T2 prolongation due to increased intracellular or extracellular free water (muscle edema), is best detected with inversion-recovery and fat-suppressed T2-weighted images (, 1,, 2 ). Can a person have such a finding and still be normal? The same conclusions and observations would not necessarily apply in other situations, such as if the sequence were a phase-sensitive inversion recovery one, for example. [5] Hyperintensities appear as "bright signals" (bright areas) on an MRI image and the term "bright signal" is occasionally used as a synonym for a hyperintensity.
