Easy-to-use augmented reality neuronavigation using a wireless tablet PC.
Augmented reality (AR) technology solves the problem of view switching in traditional image-guided neurosurgery systems by integrating computer-generated objects into the actual scene. However, the state-of-the-art AR solution using head-mounted displays has not been widely accepted in clinical applications because it causes some inconvenience for the surgeon during surgery. ⋯ The easy-to-use Tablet-AR system presented in this study is accurate and feasible in clinical applications and has the potential to become a routine device in AR neuronavigation.

Impact of preoperative functional magnetic resonance imaging during awake craniotomy procedures for intraoperative guidance and complication avoidance.
We wanted to study the role of functional MRI (fMRI) in preventing neurological injury in awake craniotomy patients as this has not been previously studied. ⋯ The routine use of fMRI was not useful in identifying language sites as performed and, more importantly, practiced tasks failed to prevent neurological deficits following awake craniotomy procedures.

Integration of magnetoencephalography-generated functional brain maps into dose planning during arteriovenous malformation radiosurgery.
Magnetoencephalography (MEG) can delineate critical regions of the cortex and facilitate conformal stereotactic radiosurgery (SRS) dose planning. Despite the substantial role of Gamma Knife® SRS in arteriovenous malformation (AVM) management, MEG-generated maps of critical regions have never been utilized to improve dose planning. ⋯ Coregistration of MEG data improves the accuracy and dose sparing needed for optimal planning during Gamma Knife SRS.

A personalized stereotactic fixture for implantation of depth electrodes in stereoelectroencephalography.
The stereoelectroencephalographic (SEEG) implantation procedures still represent a challenge due to the intrinsic complexity of the method and the number of depth electrodes required. ⋯ The custom stereotactic fixture design greatly simplifies the planning procedure and significantly reduces the time in the operating room, while maintaining a high accuracy.

Increasing infection rate in multiple implanted pulse generator changes in movement disorder patients treated with deep brain stimulation.
Deep brain stimulation has been performed at the Department of Neurosurgery, Aarhus University Hospital (AUH), for 16 years. The risk of infection related to implantable pulse generator (IPG) replacement constitutes a weakness in the long-term DBS treatment. ⋯ This study found significantly different rates of infection related to the number of IPG changes. Further investigation and resources should be directed towards improving the lifespan of IPGs.
