Summary
Intra-operative MRI provides real-time imaging for neurosurgery, improving tumor resection and minimizing complications. This advanced technique enhances surgical navigation and patient safety.
Area of Science:
- Neurosurgery
- Medical Imaging
- Surgical Technology
Background:
- Existing image-guided surgical techniques lack intra-operative dynamic information.
- Advancements in surgical navigation are crucial for improving patient outcomes.
Purpose of the Study:
- To evaluate the utility of intra-operative Magnetic Resonance Imaging (MRI) for neurosurgical procedures.
- To assess the impact of real-time MRI guidance on surgical precision and safety.
Main Methods:
- Installation of the first vertical open 0.5T MRI-scanner for intra-operative use in Germany.
- Performance of various neurosurgical procedures including biopsies, craniotomies, and tumor resections under intra-operative MRI guidance.
- Development and adaptation of MR-compatible instruments and navigation systems.
Main Results:
- Intra-operative MRI enabled precise localization and targeting of intracranial lesions.
- Real-time imaging accommodated intra-operative anatomical changes, unlike traditional navigation systems.
- Development of specialized MR-compatible instruments facilitated complex surgical procedures.
Conclusions:
- Intra-operative MRI significantly aids in navigating and defining tumor margins for complete and safe resection.
- The technology reduces surgical complications and minimizes the risk of neurological deterioration.
- Interventional MRI represents a major advancement in neurosurgical practice.
