Journal of Diagnostic Medical Sonography, 1997
Ever since the beginnings of clinical radiology, two main factors have contributed to diagnostic progress: technological advance and the development of safe and reliable contrast agents. Often, these two factors have been inextricably linked. Many of today’s accomplishments in X-ray, CT, MRI, and nuclear medicine would be unthinkable without the use of

Der Radiologe, 2004
Ultrasound contrast agents consist of tiny gas bubbles encapsulated by a stabilising membrane or shell. When combined with recent contrast-specific ultrasound techniques, they provide substantial enhancement of vessels and solid organs. The clinical use and the diagnostic value of ultrasound contrast agents are in principle comparable to those of ...

Journal of Drug Delivery Science and Technology, 2013
Microbubbles, developed as ultrasound contrast agents for vascular imaging are valuable theranostic agents for multiple biomedical applications. The utility of these agents can be attributed to their unique response to ultrasound. When exposed to an acoustic pulse, microbubbles can resonate to create a strong acoustic signal that can be used to ...

Contrast Agents in diagnostic ultrasound
Ultrasound in Medicine & Biology, 1989We review the field of contrast agents in diagnostic ultrasound. The progress in the development of various classes of contrast agents such as free and encapsulated gas bubbles, colloidal suspensions, emulsions, and aqueous solutions is described. The mechanisms for production of backscatter contrast, as well as attenuation contrast and speed of sound ...

The Journal of the Acoustical Society of America, 2008
New ultrasound contrast agents that comprise microbubbles encapsulating a gas within a shell made from a blend of bipolar compounds having mixed carbon chain length. The compounds have hydrophobic groups selected from the group consisting of straight-chained alkyls, alkylethers, alkylthiolethers, alkyldisulfides, polyfluoroalkyls, and ...

Investigative Radiology, 1991
Two concepts of microbubble stabilization led to reproducible, industrially manufactured contrast agents, and to the transpulmonary stability of agents after intravenous injection. The albumin microencapsulation concept is represented by Albunex (Molecular Biosystems, San Diego, CA), the saccharide microparticle concept is represented by SH U 454 ...

Radiologic Clinics of North America
This chapter reviews the methods that have been developed and used for assessment of the microvasculature by dynamic contrast-enhanced ultrasound (DCE-US). Starting from fundamental concepts describing the physics of the ultrasound contrast agents (UCA) acoustic response behind contrast-specific imaging sequences, it discusses the conversion from ...

Ultrasound contrast agents: A review
Ultrasound in Medicine & Biology, 1994During the past 25 years, many attempts have been made to establish effective ultrasound contrast agents for both cardiac and noncardiac applications. The ideal ultrasound contrast agent would be: (a) nontoxic; (b) injectable intravenously; (c) capable of passing through the pulmonary, cardiac and capillary circulations; and (d) stable for ...
