Paper Abstract

Photoacoustic tomography can provide high resolution 3D images of vascular networks, making it well suited to characterising the development of tumour vasculature and its response to treatment. In this study, photoacoustic images to depths of up to 9 mm were obtained using an all optical ultrasound detection scheme. Two type of colorectal tumours (LS174T and SW1222) implanted subcutaneously in a mouse were studied. 3D photoacoustic images were obtained in vivo revealing the different vascular architectures of each tumour type and their evolution over a period of several days. The results suggest that photoacoustic imaging could play a role in providing essential pre-clinical information on tumour pathophysiology and eliciting the biological mechanisms underlying anti-angiogenic therapies and other treatments.
