Key result
Combined photoacoustic and ultrasound imaging offers complementary vascular assessment for potential continuous monitoring.
Why the study?
Current vascular imaging modalities have limitations for repeated vascular phenotyping without ionizing radiation, fast acquisition, and tissue composition sensitivity, motivating evaluation of photoacoustic and ultrasound imaging for clinical cardiovascular decision-making.
Integration of ultrasound and photoacoustic imaging offers a potential route toward continuous, operator-independent vascular phenotyping for clinical decision-making in cardiovascular disease.
Supports integrated photoacoustic-ultrasound vascular phenotyping in research; leaves open clinical translation pending penetration, accuracy, and endpoint validation.
Purpose of Review Photoacoustic and ultrasound imaging together resolve vascular structure, wall biomechanics, blood flow, oxygenation, and tissue composition without ionizing radiation or iodinated contrast. This review summarizes what each modality can now measure in patients and asks which of these measurements are close enough to clinical use to inform cardiovascular management decisions. Recent Findings Recent advances have expanded photoacoustic imaging toward faster, higher-resolution functional vascular phenotyping, including clinically relevant biomarkers and co-registered ultrasound imaging. Ultrafast and super-resolution ultrasound now quantify vascular biomechanics, hemodynamics, and microvasculature, with ultrasound localization microscopy entering clinical studies. Wearable ultrasound has also been validated for blood-pressure monitoring across diverse care settings, alongside increasingly quantitative feature extraction. Summary Ultrasound and photoacoustic imaging provide complementary vascular information: ultrasound offers depth, speed, and continuous access, while photoacoustic imaging adds compositional and oxygenation contrast. Despite limitations in quantitative accuracy, imaging depth, and system standardization, emerging patient studies now span super-resolution vascular mapping, functional biomarkers, and wearable monitoring. Their integration offers a potential route toward continuous, operator-independent vascular phenotyping for clinical decision-making.
