Photoacoustic imaging for assessment of peripheral perfusion in human fingers during venous and arterial occlusion

Key Points

• Peripheral perfusion assessment can be effectively achieved using photoacoustic imaging, supporting its utility in clinical settings.
• The study reveals that changes in blood flow during arterial and venous occlusions can be visualized through advanced imaging techniques.
• Assessment using photoacoustic imaging shows significant differences in perfusion metrics between arterial and venous conditions.
• Utilization of this imaging modality may enable better understanding and management of circulatory issues in fingers.
