Figure/Graphic 2a-b: DTI-FT
Example of integration of intraoperative neurophysiology with advanced MR imaging (DTI-FT) in a case of a left rolandic tumour. In this case, at the beginning of the resection the surgeon should integrate information coming from DES cortical mapping (a) (left and middle panel showing hand motor responses from the hand obtained by train of 5 techniques [left panel]) and 60 Hz probes [middle panel]), to those obtained by DTI-FT. The right panel shows the DTI-FT reconstruction for CST (in white) superimposed onto post-contrast T1-weighted images. The green cross indicates the position of the cortex where DES found hand motor responses. The site corresponded to the CST as indicated by DTI-FT images. The same type of integration is shown during resection at the subcortical level (b). The green cross indicates the site where DES (with both train of 5 techniques and 60 Hz) located hand responses from the subcortical of the CST, which corresponded to the same position in the DTI-FT images.
