Summary
This study demonstrates a 3D imaging technique using MRI, CT, and angiography to guide deep brain lesion removal. It enables precise surgical planning by visualizing the lesion, critical brain structures, and blood vessels.
Area of Science:
- Neurosurgery
- Medical Imaging
- Computer-Aided Surgery
Background:
- Microsurgical resection of deep-seated cerebral lesions presents significant challenges due to anatomical complexity.
- Accurate pre-operative visualization and intra-operative guidance are crucial for successful outcomes.
Purpose of the Study:
- To present a stereotactic neuroradiological data acquisition and 3D rendering method for guided microsurgical resection.
- To enhance surgical precision for deep-seated brain lesions.
Main Methods:
- Utilized data from magnetic resonance imaging (MRI), computed tomography (CT), and digital angiography.
- Developed a method for stereotactic acquisition, identification of cerebral structures, and 3D rendering.
- Enabled 'wire framing' of lesion volume, cerebral vessels, and functionally relevant structures.
- Created 3D renderings of surgical instruments relative to reconstructed anatomy for trajectory planning.
Main Results:
- Successfully applied the described method to guided microsurgical resection of deep-seated cerebral lesions.
- The technique allows for detailed visualization of lesion boundaries and critical neurovascular structures.
- 3D rendering facilitated effective planning and simulation of surgical approaches.
Conclusions:
- Stereotactic data acquisition and 3D rendering provide a valuable tool for neurosurgical planning and execution.
- This integrated imaging approach improves the safety and efficacy of resecting deep brain lesions.
- The method aids in simulating surgical trajectories, optimizing operative strategy.
