The purpose of this study was to analyze the feasibility and utility of 3D imaging to help lead positioning during a deep brain stimulation (DBS) procedure. A bilateral subthalamic DBS procedure was conducted in 2 patients for idiopathic Parkinson's disease. Subthalamic nucleus targeting was based on preoperative stereotactic MRI. We used the Medtronic O-arm to perform 2D-imaging control (frontal and lateral) as well as quick (<30 s) 3D acquisition. This allowed us to check the positioning of micro-macro electrodes and definite electrodes. 3D images were fused with postoperative CT to assess their accuracy, and with preoperative MRI to visualize the anatomical location of the electrodes. 3D imaging is a quick and safe method to ensure perioperative control of lead placement during DBS procedures.
