The first book to cover the groundbreaking development and clinical applications of Magnetic Resonance Elastography, this book is essential for all practitioners interested in this revolutionary diagnostic modality. The book is divided into three sections. The first covers the history of MRE. The second covers technique and clinical applications of MRE in the liver with respect to fibrosis, liver masses, and other diseases. Case descriptions are presented to give the reader a hands-on approach. The final section presents the techniques, sequence and preliminary results of applications in other areas of the body including muscle, brain, lung, heart, and breast.

Elastography, the science of creating noninvasive images of mechanical characteristics of tissues, has been rapidly evolving in recent years. The advantage of this technique resides in the ability to rapidly detect and quantify the changes in the stiffness of soft tissues resulting from specific pathological or physiological processes. Ultrasound elastography is nowadays applied especially on the liver and breast, but the technique has been increasingly used for other tissues including the thyroid, lymph nodes, spleen, pancreas, gastrointestinal tract, kidney, prostate, and the musculoskeletal and vascular systems. This book presents some of the applications of strain and shear-wave ultrasound elastography in hepatic, pancreatic, breast, and musculoskeletal conditions.

Of particular interest are chapters on the latest techniques in Patient-specific 3D printing and transient elastography (FibroScan). The final part focuses on treatment and provides a step-by step guide to the therapeutic management of liver diseases starting with pharmacological treatment and techniques including surgery and liver transplantation. This is an invaluable book for clinicians, practitioners including academics, scientists/researchers and postgraduates to provide the newest knowledge in the field of liver pathogenesis. It is written by a multidisciplinary team of experts in hepathology, gastroenterology, and surgery especially from liver transplantation.

Ultrasound-based elastography techniques have received considerable attention in the last years for the noninvasive assessment of tissue mechanical properties. These techniques have the advantage of detecting tissue elasticity changes occurring in various pathological conditions and are able to provide qualitative and quantitative information that serves diagnostic and prognostic purposes. For liver applications and especially for the noninvasive assessment of liver fibrosis, ultrasound-based elastography has shown promising results. Several ultrasound elastography techniques using different excitation methods have been developed. In general, these techniques are classified into strain elastography, which is a semi-quantitative method that uses internal or external compression for tissue stimulation, and shear wave elastography, which measures the ultrasound-generated shear wave speed at different locations in the tissue. All liver elastography techniques have a standardized examination technique, with the patient in a supine position, while the measurements are performed through the right liver lobe. There are also some confounding factors that need to be taken into account when performing liver elastography such as a higher level of aminotransferases, infiltrative liver disease, liver congestion, cholestasis. This chapter briefly introduces the basic principles of liver elastography and discusses some important clinical aspects of elastography, such as the examination technique and the limitations.

Completely revised new edition of the premier reference on pediatric liver disease. Liver Disease in Children, 3rd Edition provides authoritative coverage of every aspect of liver disease affecting infants, children, and adolescents. The book offers an integrated approach to the science and clinical practice of pediatric hepatology and charts the substantial progress in understanding and treating these diseases. Chapters are written by international experts and address the unique pathophysiology, manifestations, and management of these disorders in the pediatric population. The third edition has been thoroughly updated and features new contributions on liver development, cholestatic and autoimmune disorders, fatty liver disease, and inborn errors of metabolism. With the continued evolution of pediatric hepatology as a discipline, this text remains an essential reference for all physicians involved in the care of children with liver disease.

Magnetic resonance elastography (MRE) is a medical imaging technique that combines magnetic resonance imaging (MRI) with mechanical vibrations to generate maps of viscoelastic properties of biological tissue. It serves as a non-invasive tool to detect and quantify mechanical changes in tissue structure, which can be symptoms or causes of various diseases. Clinical and research applications of MRE include staging of liver fibrosis, assessment of tumor stiffness and investigation of neurodegenerative diseases. The first part of this book is dedicated to the physical and technological principles underlying MRE, with an introduction to MRI physics, viscoelasticity theory and classical waves, as well as vibration generation, image acquisition and viscoelastic parameter reconstruction. The second part of the book focuses on clinical applications of MRE to various organs. Each section starts with a discussion of the specific properties of the organ, followed by an extensive overview of clinical and preclinical studies that have been performed, tabulating reference values from published literature. The book is completed by a chapter discussing technical aspects of elastography methods based on ultrasound.
