Fig 4. Graphs show diffusion tensor imaging parameters for major white matter tracts in the brain stem.

A, Fractional anisotropy (FA). B, Apparent diffusion coefficient (ADC). Data are shown for the corticospinal (CS, blue bars), transverse pontine (TP, red bars), and medial lemnisci (ML, yellow bars). Subject groups included patients with pontine tumors, patient control (PAT), and healthy volunteer (VOL) groups.
