Figure 2. Watershed oxygen extraction fraction (OEF) is associated with loss of microstructural integrity.

Figure 2.

Watershed cerebral blood flow (CBF) was not associated with (A) fractional anisotropy (FA) or (B) mean diffusivity (MD) in a common normal-appearing white matter region. However, elevated watershed oxygen extraction fraction (OEF) ratio was associated with (C) decreased FA and (D) elevated MD.
