AN IN VIVO VALIDATION OF THE APPLICATION OF ACOUSTIC RADIATION FORCE TO ENHANCE THE DIAGNOSTIC UTILITY OF MOLECULAR IMAGING USING 3-D ULTRASOUND
ULTRASOUND IN MEDICINE AND BIOLOGY, 38(4), 651–660.
author keywords: Microbubble; Molecular imaging; Targeted imaging; Radiation force
MeSH headings : Animals; Contrast Media / administration & dosage; Contrast Media / chemical synthesis; Elasticity Imaging Techniques / methods; Equipment Design; Fibrosarcoma / diagnostic imaging; Fibrosarcoma / pathology; Image Enhancement / methods; Imaging, Three-Dimensional / methods; Microbubbles; Molecular Imaging / methods; Rats, Inbred F344; Sensitivity and Specificity; Transducers
TL;DR:
This is the first noninvasive in vivo validation of ARF-enhanced MI with an unmodified clinical system and demonstrates that a 78% increase in image intensity from targeted microbubbles can be achieved when using ARF relative to the passive targeting studies.

DECAFLUOROBUTANE AS A PHASE-CHANGE CONTRAST AGENT FOR LOW-ENERGY EXTRAVASCULAR ULTRASONIC IMAGING
ULTRASOUND IN MEDICINE AND BIOLOGY, 37(9), 1518–1530.
author keywords: Ultrasound; Microbubble; Contrast agent; Perfluorocarbon; Acoustic droplet vaporization
MeSH headings : Acoustics; Contrast Media / chemistry; Fluorocarbons / chemistry; Microbubbles; Microvessels; Nanoparticles / chemistry; Transducers; Ultrasonography / methods
TL;DR:
It is shown that decafluorobutane, which is normally a gas at room temperature, can be incorporated into metastable liquid sub-micron droplets with appropriate encapsulation methods and are activatable with substantially less energy than other favored PCCA compounds.

Effect and Distribution of Contrast Medium after Injection into the Anterior Suprachoroidal Space in Ex Vivo Eyes
Investigative Opthalmology & Visual Science, 52(8), 5730.
MeSH headings : Age Factors; Animals; Anterior Chamber / diagnostic imaging; Anterior Chamber / metabolism; Choroid / diagnostic imaging; Choroid / metabolism; Contrast Media / pharmacokinetics; Dogs; Drug Delivery Systems; Imaging, Three-Dimensional; In Vitro Techniques; Injections, Intraocular / methods; Latex / pharmacokinetics; Microbubbles; Posterior Eye Segment / diagnostic imaging; Posterior Eye Segment / metabolism; Retina / diagnostic imaging; Retina / metabolism; Swine; Ultrasonography
TL;DR:
The authors' hypothesis that a single anterior SCS injection can reach the ocular posterior segment was supported and it is suggested that the SCS can expand, in a dose-dependent manner, to accommodate various volumes of fluid and that it is possible to image theSCS with ultrasound contrast.
