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.

Recent advancements in nano/micro materials and related characterization approaches allow the design of a new type of ultrasound contrast agents (UCAs) with enhanced multifunctional behaviour. This is chance is also supported by the recent achievements in modelling and signal processing. This book provides the state of art of the research activity of two successful European projects, TAMIRUT and SIGHT, addressing an integrated system, encompassing the contrast agent, the hardware equipment and the processing strategies, as a key tool for a combined diagnostic and therapeutic approaches (theranostics) in medical ultrasound. The work provides a highlight of the state of art in the research of novel ultrasound contrast agents (UCAs). Main progresses on the multifunctional aspects of next-generation UCAs concern targeting and drug release properties, perfusion and biointerface behaviour, ultrasound scattering performance, signal processing, electronic equipment.

This book is a comprehensive guide to the rapidly evolving field of contrast-enhanced ultrasound (CEUS) in the child. The uses and interpretation of CEUS are clearly explained with the aid of numerous illustrations. The coverage encompasses both established indications, such as focal liver lesions, abdominal solid organ injury, and vesicoureteral reflux, and a range of newer applications. Extensive information is also provided on microbubble agents and their use in the pediatric age group, as well as on practical aspects of setting up a CEUS service for children. CEUS is a safe imaging method that is ideal for the young patient and can be used for problem solving in a number of clinical situations. Ultrasound combined with microbubble contrast avoids the ionizing radiation of a CT examination, the use of iodinated contrast, the need for sedation or a general anesthetic, and the complexities of MR imaging. In bringing readers up to date with best practice and the latest innovations in CEUS, this book will be of value for pediatric radiologists, pediatric sonographers/technicians, and pediatricians.

This book provides a comprehensive analysis of the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of a wide variety of pathologies. Sonography reliably identifies a wide range of diseases, and the efficacy of modern ultrasound has dramatically improved with contrast enhancement. This book covers almost all aspects of CEUS starting from basic principles and ending with features of its application in individual organs. In particular, it explores the diseases of abdominal, retroperitoneal, and pelvic organs as well as superficial structures, highlighting the characteristic features of typical findings. Focal lesions are discussed in depth, with attention to their early detection and differential diagnosis. Besides, a practical approach to the stratification of the risk of malignancies is provided. The authors summarized their own experience with CEUS in oncology, hepatology, gynecology, urology, endocrinology, and other fields of medicine. The role of CEUS in differential diagnosis of various disorders of the female reproductive system is comprehensively discussed as well. The presentation is clear and concise, and richly illustrated. The book will be a helpful tool for both residents and practitioners approaching ultrasound diagnostics, as well for more experienced radiologists and other professionals.

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.
