case_images: Tractography planning from StealthViz (a-b) and nordicBrainEx (c-d). Red color represents fiber tracts from corpus callosum, green color the tracts from motor and sensory area on the left side, and yellow the same tracts on the right side. Dark blue represents the arcuate fasciculus and purple shows the optic nerves.

case_images: The five fiber tracts that we focused on in this study can be seen in Figure 3, it shows the side views tractography planning from the two surgical planning software platforms: Figures 3(a) and 3(b) for StealthViz and Figures 3(c) and 3(d) for nordicBrainEx.
case_images: Comparison between the corpus callosum tracts obtained with different software: nordicBrainEx (a) and StealthViz (b). Both (a) and (b) show the same slice.

case_images: In order to assess the results from the two fiber tracts planning, we use image comparison software called XERO viewer; here, the fiber tracts, superimposed on the MRI data, were viewed simultaneously and visually assessed.  Figure 4 shows the comparison of corpus callosum. To be noticed, the surface of corpus callosum is shown in Figure 4(b) that displays a false positive.
case_images: 3D computer model made in mimics with fiber tracts result from nordicBrainEx (a) and when it has been 3D printed and painted (b).

case_images: The quantitative results are displayed in Table 3 where for this study case, the tractography plane made with nordicBrainEx has a better score and was chosen for the next step.  Figure 5 shows the computer model (a) and 3D-printed model (b) resulting from the nordicBrainEx surgical planning.
