Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up. Doctors typically provide answers within 24 hours. 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. WMH's are also referred to as Leukoaraiosis and are often found in CT or MRI's of older patients. Dr. A, I recently had an MRI and the radiologist reading is as follows: Some minimal T2 signal abnormality is noted in the periventricular white matter of the atria of the lateral ventricle, right greater than left.

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. This is often due to a combination of atherosclerosis, demyelination (loss of the "white matter" covering the nerves ), and scarring. Stark DD, Bradley WG, Bradley WG.
