Figure 3. Diffusion tensor ellipsoids (above) and apparent diffusion coefficient (ADC) profiles (below). Eigenvalues ( x 10^–6 mm² s^–1): (a) class I: 781, 670, 670; (b) class II: 1042, 529, 529; (c) class II: 1773, 164, 164; (d) class III: 931, 931, 283. Trace=2100 x 10^–6 mm² s^–1. All ellipsoid axes in arbitrary spatial units. All ADC profile axes in 10^–6 mm² s^–1.
