Who wrote the music and lyrics for Kinky Boots? In an MRI report, the white spots might be described as: "High signal intensity areas". 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 ). Usually this is due to an increased water content of the tissue. There is mild heterogeneous t2 signal change within the supraspinatus and subscapularis.what does that mean? The prevailing view is that these intensities are a marker of small-vessel vascular disease and in clinical practice, are . The above discussion presumes we are dealing with a "standard" magnitude-reconstructed spin-echo image. 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.
