N2 - Deep brain stimulation (DBS) has developed into an established therapy for the treatment of movement disorders, most commonly Parkinson's disease and tremor of different etiology. The subthalamic nucleus (STN) has evolved as the preferred target for DBS in patients with idiopathic Parkinson's disease. The principal target for DBS in tremor patients is the ventrolateral thalamus which has been explored for ablative procedures (thalamotomy) for some decades. Detailed information about the exact site of chronic stimulation, i.e. the location of the active electrode contacts, are important to map the actual subcortical structures modulating the therapeutic effects of DBS. We compared two different methods not requiring intra-operative teleradiography to determine the stereotactic coordinates of single electrode contacts, (i) correlation of pre- and post-operative MRI, and (ii) post-operative stereotactic skull x-ray. For seven patients implanted bilateral with quadripolar DBS electrodes the coordinates for each contact were determined by both approaches. This revealed for a total of 56 electrode contacts a median euclidean 3D-difference between both methods of 1.18 mm (range 0.42 to 1.93 mm). These data suggest that both approaches may be used to determine the position of single electrode contacts.
