Another possible cause of these white matter lesions could be Lyme disease. Almost immediately, they lose coherence as some spin slightly faster than the others. T2 relaxation, also known as spin-spin relaxation or transverse relaxation, refers to the progressive dephasing of spinning dipoles resulting in decay in the magnetization in the transverse plane (Mxy). The magnitude of the MR signal after an RF-pulse is in turn, dependent on two factors: T1 reflects the length of time it takes for regrowth of.

MeSH In pure water T2 is long, about 3-4 seconds because water molecules move considerably faster than the Larmor frequency. Many of the lesions may not be causing obvious symptoms. While the overall length of stay in the hospital was similar between patients with and without an increase in the T2 signal intensity (12.5 vs 10.3 days, respectively, p = 0.22), patients with an increased T2 signal intensity spent significantly more time in the ICU, and there was a strong trend toward an increased length of dependence on .

My mri states: there is a single region of three foci of t2 prolongation within the white matter. T2/FLAIR lesions can directly account for some symptoms. QT prolongation is the medical term for an extended interval between the heart contracting and relaxing. Fortunately, some treatments can prevent up to 90% of these lesions from forming. 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 How do you treat inflammation of the supraspinatus tendon? For example, a brainstem lesion can cause room spinning sensations and balance problems. 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).
