Fig 2. Magnitude of ΔT₁ in non-enhanced lesion areas.

Shown are images from three separate participants (A: SPMS/female/53, B: RRMS/female/52, C: SPMS/female/61). Color maps of ΔT₁ (units: s) in NEL’s were overlaid upon T₁-weighted images. Each color bar (not scaled) displays the full range of ΔT₁ only within NEL of the corresponding participant. Three representative participants shown for display purposes (analysis was in all subjects). Each row shows three consecutive image slices of a single participant. SPMS = secondary progressive multiple sclerosis; RRMS = relapsing-remitting multiple sclerosis; BBB = blood-brain barrier; NEL = non-enhancing lesion.
