Intraoperative imaging techniques for glioma surgery.

Area of Science:

• Neurosurgery
• Medical Imaging
• Oncology

Background:

• Gliomas are brain tumors that infiltrate brain tissue, making surgical treatment challenging.
• Maximizing tumor resection while preserving neurological function is critical for improving glioma patient prognosis.
• Current surgical approaches for gliomas utilize tools like intraoperative MRI, ultrasound, and fluorescence-guided microsurgery.

Purpose of the Study:

• To review the advantages and limitations of various intraoperative imaging techniques for glioma identification.
• To discuss the role of established and emerging technologies in enhancing surgical resection of gliomas.

Main Methods:

• Review of established intraoperative imaging modalities (MRI, ultrasound, fluorescence-guided surgery).
• Discussion of emerging experimental techniques (optical coherence tomography, Raman spectroscopy).
• Analysis of the potential benefits and drawbacks of each technique in the operating room setting.

Main Results:

• Intraoperative MRI, ultrasound, and fluorescence-guided microsurgery are valuable tools for increasing glioma resection extent.
• Emerging techniques like optical coherence tomography and Raman spectroscopy show promise for future glioma surgery.
• Each imaging modality presents unique advantages and limitations that must be considered for optimal application.

Conclusions:

• Optimizing surgical resection of gliomas requires advanced intraoperative imaging tools.
• Established and emerging imaging technologies can significantly improve the identification and resection of gliomas.
• Careful consideration of the benefits and limitations of each technique is essential for improving glioma surgical outcomes.
