Figure 1 (IMAGE) Radiological Society of North America Caption Structural and microstructural MR imaging markers of subclinical brain damage. The left side of each image corresponds to right side of the brain. A, T1-weighted image. B, Fluid-attenuated inversion recovery image shows white matter lesions (arrowhead) and lacunar infarct (arrow). C, Three-dimensional T2* gradient-echo MR image shows cerebral microbleeds (arrow). D, Tissue segmentation, with each tissue type represented by a different color. CSF = cerebral spinal fluid, GM = gray matter, WM = white matter. E, Diffusion-tensor imaging map of fractional anisotropy. F, Diffusion-tensor imaging map of mean diffusivity. Credit Radiological Society of North America Usage Restrictions May use with credit.
