Contrast-Enhanced Ultrasound in Clinical Practice, Liver, Prostate, Pancreas, Kidney and Lymph Nodes
The worth of ultrasound contrast agents (USCA) in daily medical practice depends on the pharmacokinetics, the signal processing, and the contrast-specific imaging modalities. Second-generation USCA, are blood pool representatives that do not leak into the organ tissue to be examined however remain in the intravascular compartment increasing the Doppler signal amplitude during their dynamic vascular stage. Benefiting from the stability of their microbubbles, they can hold up against the acoustic pressure of insonation much better than first-generation contrast media, which leads to an increased half-life of the agent and, consequently, in an extended diagnostic window. Concomitant with the enhancement of contrast agents, different contrast-specific imaging methods have been developed which, used in mix with USCA and a low mechanical index, permit constant real-time grey-scale imaging. These recent technical improvements have actually opened brand-new possibilities in making use of USCA in a range of signs. Written by globally popular specialists, the contributions collected in this book give an introduction of existing and possible future new applications of USCA in regular and medical practice.
