Survival intravascular photoacoustic imaging of lipid‐rich plaque in cholesterol fed rabbits
Abstract Intravascular photoacoustic (IVPA) imaging is a promising modality for quantitative assessment of lipid‐laden atherosclerotic plaques. Yet, survival IVPA imaging of the same plaque in the same animal is not demonstrated. Here, using a sheathed IVUS/PA catheter of 0.9 mm in diameter, we demo...

| description | Abstract Intravascular photoacoustic (IVPA) imaging is a promising modality for quantitative assessment of lipid‐laden atherosclerotic plaques. Yet, survival IVPA imaging of the same plaque in the same animal is not demonstrated. Here, using a sheathed IVUS/PA catheter of 0.9 mm in diameter, we demonstrate MRI‐guided survival IVPA imaging of same plaque in an aorta of a well‐established rabbit model mimicking atherosclerosis in human patients. The IVUS/PA results were confirmed by histology. These advances open the opportunity to evaluate the effectiveness of a therapy that aims to reduce the size of atherosclerotic plaques and demonstrates the potential of translating the IVPA catheter into clinic for detection of lipid‐rich plaques that are at high risk for thrombosis. |
