Abstract

Intravascular photoacoustics (IVPA)—a minimally invasive imaging technique with contrast related to optical absorption properties of tissue, can be used to visualize atherosclerotic plaques. However, the amplitude of photoacoustic signals is also related to a temperature dependent, tissue specific parameter—the Grüneisen parameter. Therefore, photoacoustic signals measured at different temperatures may reveal information about tissue composition. In this study, thermal IVPA (tIVPA) imaging was introduced. The imaging studies were performed using an ex vivo atherosclerotic rabbit aorta. Temperature dependent photoacoustic responses from lipid in plaques and lipid in periadventitial tissue were different, thus allowing tIVPA images to delineate the location of lipid-rich plaques. The results indicate that tIVPA imaging has a potential to characterize tissue composition in atherosclerotic vessels.

(a) IVUS and (b) combined IVUS/IVPA (1210 nm wavelength) images of the atherosclerotic vessel. The images were acquired at 25°C. Yellow arrows in these images indicate the location of atherosclerotic plaques. (c) Oil red O stain confirmed that the imaged aorta had lipid-rich plaques. The angular position of the histological slide was chosen based on the visual correlation of the shape of the vessel wall in histology and the IVUS image. (d) Comparison of the temperature dependent normalized amplitude of PA signal in plaque and the adventitia (error bars correspond to plus/minus one standard deviation).

(a) Thermal IVPA (tIVPA) and (b) spectroscopic IVPA (sIVPA) images of the same cross-section of the atherosclerotic artery. Lipid-rich atherosclerotic plaques have similar appearance in tIVPA and sIVPA images while periadventitial fat does not appear in the tIVPA image.
