Magnetic
resonance imaging provides a mean to non-invasively investigate the
neurological cause of dyslexia, a learning disability that affects ones
ability to read despite adequate intelligence. Myelin water imaging, based on calculating
the myelin water fraction from multi-echo T2 relaxation curves, can be used
to quantitatively assess white matter.
In this study, myelin water imaging and cognitive and reading
assessments were performed on children with a wide range of reading ability
in order to investigate the relationship between dyslexia and white matter
development in the brain.
