Review demonstrates intravascular photoacoustic imaging evaluates plaque structure and composition in coronary artery disease, highlighting its potential for assessing acute event risk.

Key Points

To review the capabilities and translational progress of intravascular photoacoustic imaging for identifying vulnerable atherosclerotic plaques through structural and compositional characterization.
Evaluated intravascular photoacoustic imaging (IVPA) as an optical extension of intravascular ultrasound that leverages tissue-specific optical absorption spectra.
Assessed lipid detection capabilities across ex vivo human coronary artery specimens and an in vivo animal model.
Analyzed targeted detection of additional vulnerability markers, including calcium and inflammation (macrophages and matrix metalloproteinases) using exogenous contrast agents.
IVPA successfully identified lipid-rich components of thin-cap fibroatheromas in human coronary tissue ex vivo, with proven translation to in vivo animal imaging.
Exogenous contrast agents enabled precise optical targeting and visualization of inflammatory disease markers, including macrophages and matrix metalloproteinases.
Combined morphological and compositional imaging demonstrated strong prognostic potential for monitoring disease progression and guiding percutaneous coronary interventions.
