In the last few years, the development of sonographic contrast agents - or "microbubbles" - has stimulated increasingly intensive studies on the rela tionships between ultrasound and contrast media. As a result, "contrast -spe cific" hardware and software systems have been introduced by different ultra sound manufacturers with impressive speed. This has finally led to the birth of a very new imaging modality -"contrast-enhanced sonography" (CEUS). Since 1999, the introduction of second-generation contrast agents has represented a decisive step towards the extensive clinical use of CEUS and has simultaneously made obsolete most, if not all, scientific publications available so far. This book is, to our knowledge, the first to deal entirely with second generation contrast agents and the most updated contrast-specific software for noncardiologic uses. The reasons why the liver has been chosen as the only "target" of the book are easily understandable by radiologists and hepatologists alike. The study of vascularity is the only purpose of CEUS, and the liver has a unique vascular system, with two different inflow systems resulting in a single outflow. Furthermore, the pathologically different focal liver lesions (FLLs) are mostly characterized by different "models" of vascularity: CEUS can mimic contrast enhanced computed tomography and magnetic resonance imaging, basing differential diagnosis on the morphological and temporal characteristics of enhancement, but with the additional unique advantage of the study being done in real-time.

This book aims to provide reader an overview of clinical applications of contrast-enhanced ultrasound in hepatic neoplasms diagnosis. Ultrasound images and pathological results of different hepatic neoplasms are introduced in the chapters, including benign liver tumors, malignant liver tumors, hepatic carcinoma, intrahepatic cholangiocarcinoma, rare liver benign and malignant neoplasms, regenerative nodules, inflammatory pseudotumor, parasite liver lesions, and hepatitis peliosis, etc. The combination of ultrasound findings with final histopathological results then discover the potential mechanical of contrast enhancement changes. With the development of ultrasound technology and widely application of ultrasound contrast agents (USCA) in recent decades, contrast-specific imaging modalities have been developed in combination with USCA and a low mechanical index (MI), allowing continuous real-time grey scale imaging. The updated contrast-specific software for liver diseases and hepatic tumors diagnosis has also been described described in detail. With high-resolution contrast ultrasound images during arterial phase, portal venous phase and late phase, author wants to show the whole dynamic wash-in and wash-out process of the different focal liver lesions.This book is an invaluable resource for radiologists, hepatologists and oncologists in their everyday clinical practice.

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.

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.
