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.
