Book Description
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.

Book Description
All kinds of chronic liver disease can progress into liver fibrosis, and the stage of liver fibrosis is an important prognostic factor. Therefore, assessment of liver fibrosis is of importance for the management of the chronic liver disease. Although liver biopsy is considered the standard method, its invasive nature limits clinical use. In this regard, shear wave-based ultrasound elastography has been emerged as a noninvasive method to evaluate liver fibrosis. Among various techniques, transient elastography (TE) has been the most extensively used and validated method. TE provides good diagnostic performance in staging liver fibrosis. In addition to TE, point shear wave elastography (pSWE) and two-dimensional SWE (2D-SWE) have been developed as another noninvasive method, and also reported good diagnostic performance in staging liver fibrosis. Although TE, pSWE, and 2D-SWE show good performance in assessing liver fibrosis, concurrent inflammatory activity and/or hepatic congestion are important limitations in the current elastography technique.

Book Description
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.

Book Description
This is the first comprehensive book on the new elastographic techniques discussing the early assessment of liver fibrosis. The book covers all aspects of measuring liver stiffness starting from the methodology, the molecular basis of liver stiffness elevation up to current clinical algorithms and interpretation. Future directions and novel implications that go beyond diagnosis but are relevant for understanding of liver cirrhosis per se are also discussed in detail. Liver Elastography, is an essential companion for hepatologists and gastroenterologists that provides an overview of its basic principles and gives a detailed account of how to use elastrography in clinical practice.

Book Description
The comparison between methods, evaluation of portal hypertension and many other questions are still open issues in liver elastography. New elastographic applications are under evaluation and close to being used in clinical practice. Strain imaging has been incorporated into many disciplines and EFSUMB guidelines are under preparation. More research is necessary for improved evidence for clinical applications in daily practice. The Special Issue published papers on recent advances in development and application of Ultrasound Elastography.

Book Description
This volume explores the main applications of elastographic techniques in hepatological and gastroenterological diseases, and elaborates on the use of these diagnostic techniques in a broad range of clinical settings; in this regard, it provides a clear critical methodological approach to the correct indication, taking into account the existing diagnostic pathways, the actual diagnostic accuracy of elastographic techniques, and their impact on clinical practice in terms of correct positioning of the test in the diagnostic pathway and clinical outcomes improvement. In the first chapters, which focus on the correct methodology for Diagnostic Accuracy Assessment of non -invasive techniques, the architecture of diagnostic research is discussed. In turn, the following sections describe a broad range of clinical applications in hepatology and gastroenterology. The closing section presents a number of case studies on practical issues, together with a critical discussion on how to promote the appropriate use of these technologies. Given its scope, the book will be of interest to specialists, post-graduate medical students, and researchers in the fields of hepatology and gastroenterology.

Book Description
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.
