MRI criteria for MS are based on the presence of focal lesions in the white matter (WM) of the central nervous system (CNS), which are considered typical for this condition in terms of distribution, morphology, evolution, and signal abnormalities on conventional MRI sequences (e.g., T2-weighted, T2-FLAIR, pre- and post-contrast T1-weighted scans...
Lesion assessment on conventional T 2 -weighted and post-contrast T 1 -weighted MRI sequences has allowed the definition of criteria that support the early diagnosis of multiple sclerosis in patients with clinical symptoms characteristic of multiple sclerosis (Thompson et al., 2018).
