MRI is increasingly used for the diagnosis and follow-up of people with Multiple Sclerosis (MS). However, there is a need for objective MRI biomarkers that can be used in clinical practice. This is now possible. By sending MRI data to a icometrix, reliable and objective reports of brain atrophy and lesion load can be obtained.

- 4. Barkhof et al. 2009, Lopez-Diego et al. 2009, Popescu et al. 2013 MULTIPLE SCLEROSIS Classically multiple sclerosis (MS) has been regarded as an auto-immune disease of the white matter in the central nervous system leading to severe disability over the course of several decades. Over the years, substantial evidence emerged that gray matter (GM) is also heavily affected and that neurodegenerative phenomena such as neuronal/axonal damage and GM and White Matter (WM) atrophy play an important role in MS.
