Fig 1. T2-weighted images (left) and MFC color maps (right) in a 29-year-old patient with MS (top row) and a 32-year-old control subject (bottom row). Note the clearly increased MFC in the deep gray matter regions on MFC maps (arrows) in the patient (B) relative to the control subject (D), though such a difference is not remarkable on conventional T2-weighted images (A, C).
