One that immediately comes to mind (suggested by my colleague Graeme Bydder) is the Pulsed 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). It is difficult to answer your question with this isolated finding. My MRI states: There is a single region of three foci of T2 prolongation within the white matter. In solutions of macromolecules and tissues the relaxation rate is much faster, i.e., the T2 time is shorter. Many similar examples of additive (augmenting) or subtractive (competing) image contrasts between two tissue components may be cited.

I am a having a few issues but my main concern is: i recently had a MRI of my lumbar spine to diagnose the severity of my spinal stenosis. [6], Postmortem studies combined with MRI suggest that hyperintensities are dilated perivascular spaces, or demyelination caused by reduced local blood flow. Subacute combined degeneration of the spinal cord (SCD). It can cause issues with memory, balance and mobility. Doctors typically provide answers within 24 hours. Background White matter hyperintensities (WMH) lesions on T2/FLAIR brain MRI are frequently seen in healthy elderly people. 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).

ADVERTISEMENT: Supporters see fewer/no ads. 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. In all tissues, there exist tiny magnetic fields (~1mT) generated by the spinning hydrogen nuclei (protons). T2 relaxation occurs in a varying local magnetic field when there is transfer of energy between dipoles facing parallel and antiparallel to the external magnetic field, flipping each other in opposite directions. V1/T1 = V2/T2 Where temperature must be in Kelvins 67C + 273 = 340 K So 140/340 = 50/T2 Find T2 340/140 (50) = T2 T2 = 121 K or -152C. People who have risk factors for cardiovascular disease also have a greater risk of developing white matter disease. T2/FLAIR lesions can directly account for some symptoms. 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.

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. 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 The rapid motion results in the T1 and T2 being about the same in pure water. T2 reflects the length of time it takes for the MR signal to decay in the transverse plane.

The poor blood supply and vascularity of tendons mean that is can take a long time for them to heal on there own. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 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 (M xy).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 .

Sufficient damage to the axons that course through WMH can cause adequate interference with normal neuronal functions. Long T2 fluids with few macromolecules such as water, urine, and CSF will appear bright on T2-weighted images. T2 (transverse relaxation time) is the time constant which determines the rate at which excited protons reach equilibrium or go out of phase with each other.
