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

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
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)

2014 article

In Vivo Quantification of Image Enhancement and Circulation Kinetics for Phase Change Perfluorocarbon Agents Using Custom Pulse Sequences

2014 IEEE INTERNATIONAL ULTRASONICS SYMPOSIUM (IUS), pp. 417–420.

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

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)
