We took isotropic 0.5 mm 3D SWI images to visualize small veins. The isotropic voxels allow the semi-automatic segmentation methods to track the vessels across slices. In addition we looked at the feasibility of using 3D mask from isotropic images to segment structures like the hippocampus from high in-plane resolution 2D SW images (0.2x0.2mm)
