Summary
Cancer remains the second leading cause of death worldwide (World Health Organization), involving various pathological processes across multiple biological scales . Ultrasound is increasingly used in clinical oncological practice for patient diagnosis, therapy guidance, and monitoring, however do not allow for imaging of the metabolic and vascular onset of cancer at the microscale . Here, I aim to develop multi-messenger ultrasound imaging for the early metabolic and vascular detection of cancer in a pre-clinical model and a pilot human head and neck oncology study. This interdisciplinary proposal will build on three recent breakthroughs in ultrasound and synthetic biology: (1) 4D ultrasound imaging at the millisecond timescale, (2) ultrasound super-resolution imaging at the microvascular scale and (3) biomolecular ultrasound imaging at the cellular scale.I will develop non-linear sound sheet imaging (NSSI) for the 3D imaging of ultrasound contrast agents regardless of their motion. Combined with localization algorithms, this method will enable 3D ultrasound microscopy (SSLM) of capillary networks perfused with clinically approved contrast agents. Using this vascular message we will characterize rat brain tumors in preclinical research. We will also evaluate the potential of the ultrasound microscopy technique to detect metastatic sentinel lymph nodes in a pilot human study. Furthermore, NSSI will be capable of imaging GVs that are small enough to extravasate the leaky vasculature of tumors. In this specific aim, I will rely on genetically engineered pH-sensing GVs developed in my host laboratory (NWO Start-up Grant STU.019.021 of the Dutch Research Council).
