What does it mean when a MRI (brain) says there are ten small t2 hyperintense foci within the periventricular deep white matter. [6], Postmortem studies combined with MRI suggest that hyperintensities are dilated perivascular spaces, or demyelination caused by reduced local blood flow. The rapid motion results in the T1 and T2 being about the same in pure water. and transmitted securely. I would want to know if you had an elevated CRP, sed rate or a positive ANA test. Quant Imaging Med Surg 2020; 10:1080-1120. 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 ). 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.

There are innumerable punctate T2/FLARE hyperintense lesions throughout the subcortical and periventricular white matter. The pattern of T1 lesions with contrast changes from month to month. To understand this "paradox", you must realize that apixel's "brightness" or "darkness" on an MR image is directly related to the magnitude of the detected MR signal. In pure water T2 is long, about 3-4 seconds because water molecules move considerably faster than the Larmor frequency. People who have risk factors for cardiovascular disease also have a greater risk of developing white matter disease.
