[7], White matter hyperintensities can be caused by a variety of factors including ischemia, micro-hemorrhages, gliosis, damage to small blood vessel walls, breaches of the barrier between the cerebrospinal fluid and the brain, or loss and deformation of the myelin sheath. What is the grading scale for supraspinatus tendinopathy? One of the major challenges associated with the T2 assessment according to the RANO criteria is the differentiation between T2-progress and other causes of T2 signal increase, such as edema, radiation effects, decreased corticosteroid dosing, seizures, postoperative changes, or even ischemic injury. I would want to know if you had an elevated CRP, sed rate or a positive ANA test. Sufficient damage to the axons that course through WMH can cause adequate interference with normal neuronal functions. Certainly, these findings are not diagnostic for any entity, and may represent old head injury, prior cigarette smoking, or even changes in arteries a to start having migraine at 41. With body tumors the contrast may be spectacular when the tumor T2 is increased and its D* is also decreased so that the contrast produced by both of these tissue properties is positive and synergistic. What causes increased signal in the normal supraspinatus tendon? The poor blood supply and vascularity of tendons mean that is can take a long time for them to heal on there own.
