Figure 1. Estimating Patient-Specific Surgery Network.

Figure 1

Preoperative T1-weighterd (T1w) MRI of an example patient (A) and postoperative T1w MRI (C) were used to delineate the tissue resected by surgery. Resected tissue shown by the red resection mask in panel (B) was used with the preoperative diffusion MRI to infer brain networks. Presurgery network inferred from the number of streamlines connecting different regions of interest in panel (D) ignores the surgery information by not taking the resection mask into consideration. (E) Patient-specific surgery network showing the connections that were affected by the surgery. (F) Surgically spared network. dMRI = diffusion-weighted MRI; sMRI = structural MRI.
