author keywords: Acoustic droplet vaporization; Perfluoropropane; Perfluorobutane; Microbubble; Ultrasound; Contrast agent; Phase change
MeSH headings : Animals; Contrast Media / chemistry; Contrast Media / pharmacokinetics; Fluorocarbons / chemistry; Fluorocarbons / pharmacokinetics; Kidney / blood supply; Kidney / diagnostic imaging; Kinetics; Microbubbles; Phase Transition; Rats; Rats, Inbred F344; Transducers; Ultrasonography / methods
topics (OpenAlex): Ultrasound and Hyperthermia Applications; Photoacoustic and Ultrasonic Imaging; Ultrasound Imaging and Elastography
TL;DR: Low-boiling-point nanoscale PCCAs evaluated in vivo can produce contrast enhancement similar to that of microbubbles and can be designed to circulate for as much as 3.3 times longer than microbubble. (via Semantic Scholar)

In vivo quantification of image enhancement and circulation kinetics for phase change perfluorocarbon agents using custom pulse sequences

Sheeran, P. S., Rojas, J. D., Puett, C., Hjelmquist, J., Arena, C. B., & Dayton, P. A. (2014, September 1).

By: P. Sheeran n, J. Rojas n, C. Puett  n, J. Hjelmquist n, C. Arena  n & P. Dayton n

topics (OpenAlex): Ultrasound and Hyperthermia Applications; Photoacoustic and Ultrasonic Imaging; Thermoregulation and physiological responses
TL;DR: This study develops a custom pulse sequence to vaporize and image droplets using the Verasonics research platform, and demonstrates a novel concept in contrast-enhanced ultrasound: capture of droplet-generated contrast wash-out in the target organ. (via Semantic Scholar)
