MRgFUS VIM Thalamotomy and VIM-DBS Localization.
The MRgFUS lesion is visualized in the VIM thalamus on MRI on postoperative day 1 (blue arrows) demonstrating an adequate lesion on axial T2-FLAIR (A), axial T1-weighted (B) and sagittal T1-weighted (C) images. The lesion is redemonstrated at 24 months post-MRgFUS (red arrows) on T1-weighted MRI images in the axial (D), sagittal (E), and coronal (F) planes. Following DBS surgery, post-op CT was fused to pre-operative MRI, and the DBS lead was reconstructed using Lead-DBS [38]. The DBS lead is demonstrated within the previously lesioned tissue (red outline) on 24-month post-lesion axial T1-weighted MRI (H). The predicted VIM location (yellow), derived from the DISTAL atlas [39] and projected in MNI space, is superimposed on the same T1-weighted image (G).
