Area of Science:

Neurosurgery
Medical Imaging
Neuroscience

Background:

Neurosurgery on eloquent cortex carries risks of functional deficits.
Aggressive tumor resection in these areas requires precise surgical guidance.

Observation:

Advanced biomagnetic functional imaging and surface-rendered MRI with vascular anatomy were utilized.
A novel nonintrusive intraoperative guided instrumentation system was employed for tumor resection.

Findings:

Pre-operative motor cortex localization using noninvasive mapping was highly accurate when verified intraoperatively via direct stimulation.
Combined functional and anatomical maps demonstrated clear applicability in guiding the surgery.

Implications:

This technological integration shows potential for minimizing risks in eloquent cortex neurosurgery.
Improved patient outcomes are anticipated through the use of these advanced neurosurgical techniques.
