T2 weighted image | Radiology Reference Article | Radiopaedia.org However, continued development of new brain T2/FLAIR lesions could lead to new attacks and thinking problems such as short-term memory loss or trouble keeping track of multiple tasks at the same time. 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. Sufficient damage to the axons that course through WMH can cause adequate interference with normal neuronal functions.

What is the grading scale for supraspinatus tendinopathy? Federal government websites often end in .gov or .mil. Usually this is due to an increased water content of the tissue. 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 . They are opposed, and the results are often disappointing. it also found the following: there is a focus of uniform t2 prolongation in the medial lower pole of the right kidney measuring 20 mm in diameter.
