ReviewImplantation of deep brain stimulator electrodes using interventional MRI.
The authors describe a method for placement of deep brain stimulator electrodes using interventional MRI in conjunction with a skull-mounted aiming device (Medtronic Nexframe). This approach adapts the procedure to a standard-configuration 1.5-T diagnostic MRI scanner in a radiology suite. ⋯ The method is conceptually simpler than the current standard technique for deep brain stimulator placement, as it eliminates the stereotactic frame, the subsequent requirement for registration of the brain in stereotactic space, physiologic testing, and the need for patient cooperation. With further technical refinement, the interventional MRI method should improve the accuracy, safety, and speed of deep brain stimulator electrode placement.

Intraoperative MRI (iMRI) can be applied in several surgical settings. The incorporation of MRI technology into the operating room requires special considerations. ⋯ Incorporating the MRI technology into the operating room presents a new challenge in a transdisciplinary environment. The use of the iMRI technology has provided revolutionary tools for the new generation of medical practice.
