183 MS patients, with more than one available brain MRI, were randomly selected between 03.04.2002 and 03.11.2017, for a total of 829 MRI examinations.

Inclusion and exclusion of cMRI studies	n
Randomly selected MS patients with >1 cMRI examination	183
cMRI examinations in total	829
Excluded cMRI (due to)	−178
lack of pre- or post contrast T1-WI	−120
low spatial resolution or artifacts (e.g., motion artifacts)	−58
Analyzed cMRI	651

From these, 178 MRI examinations were excluded due to lack of pre or post contrast T1-weighted images (120 examinations) and low resolution or motion artifacts (58 examinations). In total, 651 MRI examinations were analyzed in 183 MS patients, median 3 (2–4) per patient. cMRI, cerebral MRI; n, number.
