Figure 1 (image) Radiological Society of North America Share Print E-Mail 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.
