Hypoxia, or low oxygen partial pressure, is a common feature of many solid tumours, associated with therapy resistance and poor prognosis for cancer patients. This chemical feature of the tumour microenvironment represents an imbalance of blood oxygen supply and tissue oxygen demand. Given the prognostic significance of hypoxia, there is a clinical unmet need to provide validated, non-invasive, imaging biomarkers that can be used to detect and monitor the spatiotemporal distribution of hypoxia at the point of cancer diagnosis and during treatment. In this talk, I will give an overview of how photoacoustic imaging can address this unmet need, providing examples from both preclinical studies in mouse models of cancer and clinical studies in human patients.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
