Area of Science:

Neurosurgery
Medical Imaging
Computer-Aided Surgery

Background:

Development of a specialized workstation for neurosurgical stereotactic procedure planning at KUL University of Leuven.
Integration with Picture Archiving and Communication Systems (PACS) for direct image transmission to the operating theater.

Observation:

Computed Tomography (CT) and/or Magnetic Resonance (MR) images acquired under stereotactic conditions are utilized.
The workstation allows for accurate target and entry point definition on zoomed images.
Trajectory planning can be verified and adjusted across all registered datasets and resliced images.

Findings:

Maximum intensity projection of MR angiography data visualizes blood vessel proximity to the planned trajectory.
Over 32 months, 29 patients underwent surgery using the workstation.

No new postoperative neurological deficits were observed in any patient.

Implications:

The neurosurgical workstation significantly enhances patient safety.
It increases the precision of stereotactic operations by aiding surgeons in avoiding critical neurovascular structures and functional brain regions.
This technology represents a valuable advancement in neurosurgical planning and execution.
