The value of ultrasound contrast agents (USCA) in everyday clinical
practice depends on the pharmacokinetics, the signal processing,
and the contrast-specific imaging modalities. Second-generation
USCA, are blood pool agents that do not leak into the organ tissue
to be examined but remain in the intravascular compartment
increasing the Doppler signal amplitude during their dynamic
vascular phase. Taking advantage of the stability of their
microbubbles, they can withstand the acoustic pressure of
insonation much better than first-generation contrast media, which
results in an increased half-life of the agent and, consequently,
in a prolonged diagnostic window. Concomitant with the improvement
of contrast agents, different contrast-specific imaging modalities
have been developed which, used in combination with USCA and a low
mechanical index, allow continuous real-time grey-scale imaging.
These recent technical improvements have opened new possibilities
in the use of USCA in a variety of indications. Written by
internationally renowned experts, the contributions gathered in
this book give an overview of current and possible future new
applications of USCA in routine and clinical practice.
