Technical video demonstrates the use of intravascular OCT for enhanced vascular imaging in cerebrovascular treatments, highlighting implications for neurointerventions.
Endovascular therapies are increasingly becoming the primary approach for treating cerebrovascular disorders.¹,² However, these procedures rely on DSA, which provides limited visualization due to inherently limited spatial resolution.³ Intravascular optical coherence tomography (OCT) enables 3D, high-resolution visualization of coronary arteries, allowing detailed assessment of the vascular wall, atherosclerotic plaque characteristics, and stent deployment.⁴ This has lead cardiology societies to recommend intravascular OCT for the management of complex coronary interventions (level 1A evidence).⁵,⁶ OCT is now being adapted for neurointerventional applications.⁷ A dedicated neuro-OCT (nOCT™, Spryte Medical) technology, designed to enable OCT imaging in tortuous intracranial arteries, has been recently introduced.⁸ Initial studies showed nOCT safety and feasibility for neurovascular use and explored its potential value for improved intracranial vascular imaging in stroke settings.⁹ The successful integration of nOCT technology into clinical workflows requires standardized principles for image acquisition and interpretation.¹⁰,¹¹ This video describes how to use nOCT in clinical practice.
