[5] Hyperintensities appear as "bright signals" (bright areas) on an MRI image and the term "bright signal" is occasionally used as a synonym for a hyperintensity. 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 . T2/FLAIR lesions can directly account for some symptoms. They are all conncected. FOIA 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 meaning of PROLONGED is continuing for a notably long time : extended in duration. MRI found mild scattered foci of abnormal T2 signal are demonstrated in peri ventricular white matter, particularly along frontal convexities. The pictures show both old and new inflammation. ? 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).
