> When I apply a threshold filter and view as a ‘Surface’ the image is a lot more ‘blocky’ than in the other two applications.  The image is dominated by the artifactual lines due to the original data being acquired as axial slices; whereas in OsiriX and 3D Slicer this gets smoothed out and the ‘genuine’ surface skull features (sutures etc) stand out.

Try using the "Contour" filter instead of Threshold. That will give
you a surface mesh. If you want to generate a volumetric dataset, use
the "Clip" filter with "Clip Type" set to Scalar and then enter the
scalar value to clip at.
