Brain magnetic resonance imaging (MRI) is the main way healthcare providers diagnose white matter disease. An MRI scan is a painless test that produces very clear images of different parts of your body. MRI uses a large magnet, radio waves and a computer to produce these detailed images without any radiation (does not use X-rays).
White matter disease is commonly detected on brain MRI of aging individuals as white matter hyperintensities (WMH), or ‘leukoaraiosis.” Over the years it has become increasingly clear that the presence and extent of WMH is a radiographic marker of small cerebral vessel disease and an important predictor of the life-long risk of stroke, cognitive impairment, and functional disability.
Feb 16, 2022 · A magnetic resonance imaging (MRI) scan of each participant’s brain was taken each week throughout the study, allowing the researchers to observe subtle changes over time. The brain scans revealed evidence of tiny strokes appearing in the white matter of most participants over time, yet the participants did not experience any symptoms.
Apr 22, 2023 · There are many different white matter diseases. They can be caused by inflammation, vascular disease, medication, or infection and may include: Multiple sclerosis: This inflammatory demyelinating neurological condition affects the white matter of the brain and spinal cord. It causes exacerbation and remissions, meaning episodes of worsening ...
Brain MRI. A brain (head) MRI scan is a painless test that produces very clear images of the structures inside of your head — mainly, your brain. Healthcare providers use brain MRIs to evaluate, diagnose and monitor several different medical conditions that affect your brain or other structures in your head.
Oct 30, 2014 · This is your brain on aging. The human brain has a wafer-thin layer of folded grey matter on the surface, and white matter on the inside. The white matter consists of more than 100,000 kilometres of nerve fibres which connect parts of the grey matter with each other, and with the spinal cord and the rest of the body.

T1 provides quantitative information on brain water content and is therefore a potential marker for edematous brain tissue (Bastin et al., 2002). Differences in these imaging biomarkers can help identify the pathophysiological changes within NAWM and WMH in vivo; MTR and FA generally decline, and MD and T1 gradually increase during normal aging ( Hsu et al., 2008, 2010; Silver et al., 1997 ).
