FIG 1. Three examples of MS lesions (arrows) with different T1 appearance. Top, isointense lesion (FA=0.30 ± 0.06, coefficient Dav=1.10 ± 0.07 x 10-3 mm2/s); middle, mildly hypointense lesion (FA=0.27 ± 0.05, coefficient Dav=1.24 ± 0.06 x 10-3 mm2/s); bottom, severely hypointense lesion (FA=0.19 ± 0.04, coefficient Dav = 1.76 ± 0.07 x 10-3 mm2/s). For each row, from left to right: axial view fast spin-echo T2-weighted image, spin-echo T1-weighted image, coefficient Dav map, and FA map.
