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). 2018 Sep;59(9):460-464. doi: 10.11622/smedj.2018109. But opting out of some of these cookies may affect your browsing experience. Is there mild heterogeneous T2 signal change within the supraspinatus? 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 poor blood supply and vascularity of tendons mean that is can take a long time for them to heal on there own. My doctor wants me to have blood drawn, a urinalysis and an ultrasound.
