Abstract
Within 24 hours post treatment, photodynamic therapy causes a drastic reduction in tumor oxygenation and an increase in ultrasound scattering. While these trends can lead to determining acute tumor response, monitoring vascular and structural dynamics through 72 hours post treatment using ultrasound guided photoacoustic imaging provides a better insight on long-term PDT outcomes.
