Ultrasound imaging is a relatively inexpensive technology that offers safe, noninvasive point-of-care evaluation of soft tissue. Although ultrasound imaging typically confers mechanical properties, molecular information can be obtained with the addition of exogenous contrast agents. Perfluorocarbon nanodroplets (PFNDs) are emerging as a versatile class of activatable contrast agents for ultrasound imaging. The droplets, which consist of a liquid perfluorocarbon core and a stabilizing shell, produce no inherent ultrasound contrast. When exposed to an external trigger, however, they undergo a liquid-to-gas phase transition to produce gaseous microbubbles. Ultrasound imaging can visualize the resulting microbubbles with single-bubble sensitivity.
This talk presents our lab’s recent research involving PFNDs with a particular focus on cancer applications. First, the presentation will include how two different populations of PFNDs can be simultaneously visualized with custom ultrasound activation and imaging sequences to enable sensitive detection of cancer cells. Second, the presentation will highlight how the PFNDs can be modified to become a versatile vehicle for image-guided delivery of small molecule and molecular therapeutics for breast cancer. Finally, recent work on multimodal imaging of PFNDs will be shown.
