Quantification of Ultrasound Contrast Agents Using High-Frequency Ultrasound
… All experiments were conducted with FDA approved Definity® contrast agents and were performed in vitro, i.e., within a beaker or within a perfusion phantom, or in vivo, i.e., within the auricular artery of a rabbit. Estimates of the UCA concentration were obtained by comparing estimates of the …

Acoustic characterisation of ultrasound contrast agents at high frequency
… encapsulated UCAs including two clinical UCAs Definity (Lantheus Medical Imaging, USA) and SonoVue (Bracco, Italy) and one preclinical UCAs MicroMarker (untargeted) (VisualSonics, Canada) were studied using the software and techniques developed for TMM characterisation. Attenuation, …

Collapse dynamics of ultrasound contrast agent microbubbles
… different collapse thresholds; lipid-shelled Definity exhibits greater postexcitation at lower PRPAs than albumin-shelled Optison. Furthermore, by altering the size distributions of these UCAs, it is shown that the shell material has a large influence on the occurrence of postexcitation …
