Integrated IVUS-OCT Imaging for Atherosclerotic Plaque Characterization

Area of Science:

• Cardiovascular Imaging
• Medical Device Development
• Atherosclerosis Research

Background:

• Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are key imaging modalities for atherosclerosis diagnosis.
• Vulnerable plaques pose a significant risk in cardiovascular disease.
• Current methods may have limitations in fully characterizing plaque vulnerability.

Purpose of the Study:

• To develop and evaluate an integrated IVUS-OCT imaging apparatus for enhanced atherosclerosis diagnosis.
• To assess the feasibility and superiority of simultaneous dual-modality intravascular imaging.
• To improve the diagnostic accuracy of vulnerable plaques.

Main Methods:

• Development of an integrated dual-function imaging catheter with the same diameter as current clinical standards.
• Creation of a simultaneous real-time IVUS and OCT imaging system.
• Conducting ex vivo and in vivo experiments on atherosclerosis models in rabbits.

Main Results:

• Demonstration of the feasibility of the integrated IVUS-OCT imaging apparatus.
• Evidence of the superiority of the combined imaging modality in atherosclerosis assessment.
• Successful simultaneous real-time imaging achieved.

Conclusions:

• The integrated IVUS-OCT system offers a promising advancement in intravascular imaging for atherosclerosis.
• This dual-modality approach has the potential to significantly improve the detection and characterization of vulnerable plaques.
• The developed apparatus shows potential for clinical translation to enhance cardiovascular diagnostics.
