  		Fig 1. Axial gradient-echo T2*-weighted image (left; 800/26 ms [TR/TE], 5-mm section thickness, Nx = 256, Ny = 154) shows some low-signal-intensity foci associated with CAA. Corresponding SWI image (right; 85/35 ms [TR/TE], {alpha} = 20°, Nx = 512, Ny = 256, with a resolution of 0.5 mm x 0.5 mm x 2.0 mm, projected over 8 mm) shows many more associated low-signal-intensity foci.
