Contrast agents in diagnostic ultrasound

Ultrasound in Medicine and Biology, 1989
We 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 ...

CONTRAST AGENTS IN NEUROIMAGING

Neuroimaging Clinics of North America, 1994
Until there is total elimination of adverse reactions and side effects with contrast agents, there will continue to be a need for improvement. The ideal contrast agent should be efficacious, safe, water soluble, with chemical and heat stability, biologically inert, with low viscosity, with osmolality the same as human serum, with selective excretion by

Contrast agents and mechanisms

Drug Discovery Today: Technologies, 2011
MRI contrast agents are routinely used in clinical settings. Important advances in their design have been attained in the past few years to overcome sensitivity issues and to make possible molecular imaging applications by means of this modality. Besides the sensitivity enhancement of paramagnetic relaxation probes, outstanding results have been ...
