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.

Tumor ablation is undoubtedly the most exciting and high profile procedure currently in interventional radiology. This useful guide sets the standard and is one of the first comprehensive references on the subject. The editors, world-renowned in the field, have assembled recognized international authorities in their areas of expertise. The book is organized into six main sections: Introduction to Ablation, Operations, Imaging, Methods, Organ System Tumor Ablation, and Perspectives. This breadth of coverage is coupled with an easy-to-read format that facilitates the application of these new clinical techniques. Practitioners in specialties other than radiology, including internal medicine, oncology, anesthesiology, and surgery, add valuable insights that complement the book's well-rounded approach. In addition, a chapter that depicts the cancer journey by patients and their families provides a unique perspective for the reader. More than 380 photographs and diagrams clearly illustrate key concepts. The skillful combination of depth and practicality makes this text essential for anyone who is involved with and wants to expand their knowledge in the ablation field.

This book is intended as a practical manual on the use of intraoperative ultrasound (IOUS) as a tool for imaging guidance during cranial and spinal neurosurgical procedures. Full account is taken of the emergence of novel clinical applications and recent technical advances, with extensive coverage of the impact of developments such as improved probe technology, fusion imaging and virtual navigation, 3D ultrasound imaging, contrast-enhanced ultrasound, and elastosonography. Basic principles of ultrasound are elucidated in order to assist in the optimal use of IOUS and clear guidance is provided on the interpretation of imaging findings in various pathologies. Informative comparisons are also made of the use of techniques such as fusion imaging and contrast-enhanced ultrasound in general radiology and neurosurgery. The aim of the authors is to enhance the general knowledge regarding intra-operative ultrasound brain imaging, standardizing its use and exploring new techniques, leading in some way toward compensating the lack of specific training in the application of ultrasound among the neurosurgical community. IOUS is a sensitive tool that can improve surgical precision and help to reduce morbidity.
