"The book consists of nine chapters. The first 3 chapters give a broad overview of the acoustic theory for bubble-sound interaction, both linear and nonlinear. Most contrast agents are stabilized in a shell, and this shell can have a strong influence on the interaction between the bubbles and the ultrasound. The effect of the shell is given special attention, as this is not easily found in other bubble literature. Chapters 4, 5, 6 and 7 describe experimental and theoretical methods used to characterize the acoustic properties of the agents, and results of studies on some agents. Chapter 8 shows how the theory and the experimental results can be combined and used to model various phenomena by means of computer simulations. The main purpose of the simulations is to get insight into the mechanisms behind the described phenomena, not to get accurate predictions and values.

This book will familiarize the reader with recent advances in echo imaging technology with special emphasis on echo enhancing agents. Several important strides have been made in this field during the past few years, especially in the contrast enhancement of conventional and color Doppler images. The book begins with chapters on the history of contrast echocardiography, the principles of contrast echo and descriptions of new contrast agents capable of transpulmonary passage following intravenous injection. Safety issues in contrast echocardiography are also discussed. The second section of the book deals with clinical uses of echo contrast agents. Their usefulness in the identification of cardiac structures and assessment of pathological lesions using both transthoracic and transesophageal echocardiography are fully discussed. Technical and practical considerations in the use of various contrast agents are also described. The use of contrast echo in the identification of cardiac sources of embolism as well as possible mechanisms and clinical significance of spontaneous contrast echoes are also covered. Six chapters fully discuss the basics of contrast enhancement of conventional and color Doppler images and its clinical utility in the noninvasive assessment of pulmonary artery pressure, regurgitant and stenotic lesions and in the delineation of coronary arteries. Another chapter describes the non-cardiac applications of the echo contrast enhancement technique. The final section of the book investigates the role of echo contrast enhancement in quantitative cardiovascular analysis.

Diagnostic Ultrasound Imaging provides a unified description of the physical principles of ultrasound imaging, signal processing, systems and measurements. This comprehensive reference is a core resource for both graduate students and engineers in medical ultrasound research and design. With continuing rapid technological development of ultrasound in medical diagnosis, it is a critical subject for biomedical engineers, clinical and healthcare engineers and practitioners, medical physicists, and related professionals in the fields of signal and image processing. The book contains 17 new and updated chapters covering the fundamentals and latest advances in the area, and includes four appendices, 450 figures (60 available in color on the companion website), and almost 1,500 references. In addition to the continual influx of readers entering the field of ultrasound worldwide who need the broad grounding in the core technologies of ultrasound, this book provides those already working in these areas with clear and comprehensive expositions of these key new topics as well as introductions to state-of-the-art innovations in this field. - Enables practicing engineers, students and clinical professionals to understand the essential physics and signal processing techniques behind modern imaging systems as well as introducing the latest developments that will shape medical ultrasound in the future - Suitable for both newcomers and experienced readers, the practical, progressively organized applied approach is supported by hands-on MATLAB® code and worked examples that enable readers to understand the principles underlying diagnostic and therapeutic ultrasound - Covers the new important developments in the use of medical ultrasound: elastography and high-intensity therapeutic ultrasound. Many new developments are comprehensively reviewed and explained, including aberration correction, acoustic measurements, acoustic radiation force imaging, alternate imaging architectures, bioeffects: diagnostic to therapeutic, Fourier transform imaging, multimode imaging, plane wave compounding, research platforms, synthetic aperture, vector Doppler, transient shear wave elastography, ultrafast imaging and Doppler, functional ultrasound and viscoelastic models

Following the success of the first edition and the recent, continuing developments in the field of ultrasound contrast agents, Dr. Barry Goldberg and his two new co-editors have assembled an international team of experts to discuss the basic principles of ultrasound contrast agents and, more importantly for the clinician, ultrasound agents in clinical use. As well as concentrating on the physics, principles, and radiological techniques, cardiovascular applications are also included. The significant improvements in the capabilities of ultrasound contrast agents and the greater number of contrast agents thoroughly under investigation as well as those already available on the market, mean the clinician and researcher must keep abreast of all developments in this revolutionary field. This is the book which will serve that purpose.

This volume highlights and broadens our understanding of the correct use and the possible contraindications of contrast agents applied in radiology. Written by experts in the field, it not only focuses on the chemistry, physiochemical properties and pharmacokinetics of both iodinated and gadolinium-containing contrast agents, but also on the relevant safety issues such as frequency of their short- and long-term side effects and ways to avoid them nephrotoxicity risk related to the iodinated contrast agents NSF (nephrogenic systemic fibrosis) accumulation of gadolinium in the brain use of contrast agents in pediatric patients and pregnancy It also includes essential data on the use of contrast agents, such as scanning protocols, in the context of various clinical conditions. This comprehensive manual addresses all professionals involved in radiological imaging and is an invaluable tool for radiologists and technologists, as well as for residents and clinicians.

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.
