Table 2:

Patients with discordant results between 1.5T and 3T according to Barkhof MR imaging criteria

Patient No.	Clinical Presentation	Number of Fulfilled MR Imaging Criteria		Additional MR Imaging Criterion
Patient No.	Clinical Presentation	1.5T	3T	Additional MR Imaging Criterion
1	Optic neuritis	0	1	≥1 juxtacortical lesion
2	Optic neuritis	0	1	≥1 infratentorial lesion
3	Brain stem syndrome	1	2	≥9 T2 hyperintense lesions
4	Brain stem syndrome	1	2	≥9 T2 hyperintense lesions
5	Brain stem syndrome	1	2	≥1 juxtacortical lesion
6	Optic neuritis	1	2	≥9 T2 hyperintense lesions
7	Optic neuritis	1	2	≥1 infratentorial lesion
8^*	Optic neuritis	2	3	≥1 infratentorial lesion
9^*	Optic neuritis	2	3	≥9 T2 hyperintense lesions
10	Optic neuritis	3	4	≥3 periventricular lesions
11	Spinal cord syndrome	3	4	≥1 infratentorial lesion

* Patient fulfilled 3 criteria instead of 2 at 3T, and they were therefore diagnosed of having lesion dissemination in space according to McDonald diagnostic criteria.
