Raster-scanning optoacoustic mesoscopy (RSOM) was used to monitor vascular responses to vascular-targeted PDT (VTP) with Tookad & ML7710 in mice with subcutaneous xenografts, showing immediate occlusion of tumor vessels, followed by collapse of the entire vasculature. Dual-wavelength RSOM distinguishes hemoglobin from oxyhemoglobin and provides improved spatial resolution that can be used to estimate VTP treatment efficacy .
