case_images: Left: Pre-operative axial T2-weighted MRI. Stereotactic planning performed with the Brainlab Elements software shows the planned trajectories (red and blue line). Right: postoperative axial CT. The pre-calculated electrode position is projected to the CT artifacts of the real electrode (yellow on the right side, orange on the left side). The leads are located within the caudal part of the GPi. Green outline: putamen, outer orange outline: globus pallidus externus, inner orange outline: globus pallidus internus.

case_images: T1- and T2- sequences (T1 1 mm isotropic 3D with Gadolinium and T2 space 0.65 mm isotropic). The GPi could be visualized on the T2- images, as shown in Figure 1. Cartesia directional Lead, Boston Scientific), targeting the caudal part of the GPi were implanted successfully and a rechargeable as well as MRI-compatible impulse generator (Model Gevia Boston Scientific) was placed subcutaneously in the right infraclavicular region. Correct position of the leads was confirmed by postoperative computed tomography (CT) and image fusion to the planning scans in Brainlab Elements (see Figure 1).
