Academic-Industrial Partnership for Translation of Acoustic Angiography

"Acoustic angiography imaging involves a research high frequency ultrasound scanner and a prototype transducer as well as conventional b-mode ultrasound to guide the location of the imaging. The conventional ultrasound will be conducted just prior to the acoustic angiography for localization. The imaging also requires administration of Definity ultrasound contrast agent.~Acoustic angiography imaging will be performed by trained medical personnel using mild compression to eliminate motion. Total imaging time is estimated to be less than 15 minutes."

Baseline B-mode US will be performed to confirm the lesions being imaged (unless it is a subject with no lesions, then a basic B-mode US will be performed). Perflutren is a diagnostic drug that is intended to be used for contrast enhancement. The vial contains a clear, colorless, sterile, non-pyrogenic, hypertonic solution which is activated by mechanical agitation with Vialmix®.It will be dispensed in inactivated form to a study team member. The contrast agent will be activated just prior to administration (ideally to be used within 5 minutes of activation). Contrast agent Definity will be activated according to package insert instructions, including use of VialMix®, the device used to activate Definity. Administration will occur IV in coordination with staff trained specifically in contrast ultrasound imaging.The total imaging time is anticipated to be less than 30 minutes.
