Neurointerventional optical coherence tomography (nOCT) offers high-resolution imaging for cerebrovascular disorders, improving upon traditional DSA. This technology is being adapted for clinical practice to enhance intracranial vascular visualization during endovascular procedures.
Area of Science:
- Neurointerventional radiology
- Medical imaging technology
- Cerebrovascular disease management
Background:
- Endovascular therapies are standard for cerebrovascular disorders, but rely on DSA with limited resolution.
- Intravascular optical coherence tomography (OCT) provides high-resolution 3D vascular imaging, recommended in cardiology.
- OCT is being adapted for neurointerventional applications, with a dedicated neuro-OCT (nOCT) system introduced.
Purpose of the Study:
- To describe the use of dedicated neuro-OCT (nOCT) technology in clinical practice.
- To highlight the potential of nOCT for improved intracranial vascular imaging in stroke settings.
- To emphasize the need for standardized principles for nOCT image acquisition and interpretation.
Main Methods:
- Introduction of a dedicated neuro-OCT (nOCT) system for imaging tortuous intracranial arteries.
- Evaluation of nOCT safety and feasibility in neurovascular procedures.
- Description of nOCT usage in clinical practice, including image acquisition and interpretation.
Main Results:
- Initial studies demonstrate the safety and feasibility of nOCT for neurovascular use.
- nOCT offers high-resolution, 3D visualization of intracranial arteries, surpassing DSA limitations.
- Potential value of nOCT for enhanced intracranial vascular imaging in stroke management is explored.
Conclusions:
- Neuro-OCT (nOCT) technology is a promising advancement for neurointerventional procedures.
- Standardized principles are crucial for successful clinical integration of nOCT.
- nOCT has the potential to significantly improve the diagnosis and treatment of cerebrovascular disorders.
