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)
