The hyperintense lesion could be due to a cyst or tumor. A short T2 means that the signal decays very rapidly. 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 My MRI states: There is a single region of three foci of T2 prolongation within the white matter. Cervical (neck) spinal cord T2/FLAIR lesions could cause tingling and numbness in the hands and legs. The above discussion presumes we are dealing with a "standard" magnitude-reconstructed spin-echo image. Your brain has ventricles which are fluid filled cavities on the inside of you brain. Dr. Stuart Hickerson answered Family Medicine 33 years experience MRI: Your brain has ventricles which are fluid filled cavities on the inside of you brain.

Never disregard the medical advice of your physician or health professional, or delay in seeking such advice, because of something you read on this Site. Loss of signal and darkness on T2-weighted images in cortical bone, teeth, calculi is primarily a result of little water (low proton density) unlike tendons and ligaments 3. The meaning of PROLONGED is continuing for a notably long time : extended in duration. Particular features of the focal lesions on MR images (number, size, location, presence or lack of edema, reaction to contrast medium, evolution in time), as well as accompanyi 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). My MRI shows "nonspecific, scattered foci of T2 prolongation T2/FLAIR lesions can directly account for some symptoms. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up.

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). 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 ).

This rate of flipping or transfer of energy between spins or dipoles increases as the frequency of the variation of the local magnetic field approaches the Larmor frequency. I recently had an MRI to rule out a pseudotumor cerebri.
