Liver Elastography

Sebastian Mueller is Professor of Medicine and the current vice head of the Department of Internal Medicine at Salem Medical Center and the Co-Director of the Center for Alcohol Research at the University of Heidelberg. He studied medicine in Leipzig, Denver and Strasbourg and obtained a PhD in Biophysics in 1994. He was gastroenterology resident and consultant in Heidelberg, postdoctoral Humboldt fellow at USC in Los Angeles and lecturer at the BIDMC/Harvard Medical School from 2005-2007. Prof. Mueller’s translational research includes the pathophysiology, genetics, diagnosis and treatment of liver diseases, namely alcoholic liver disease. His longterm basic research interests focus on hepatic iron metabolism and redox regulation. Prof. Mueller has published more than 100 original articles. Since 2017, he is president of the European Society of Biomedical Research on Alcoholism (ESBRA).

“This book is not aimed at radiology departments but rather at our colleagues in hepatotology and gastroenterology with the aim to offer them a deeper understanding of the role that elastography, in all its iterations, has in the assessment and management of liver disease. The book is very well written and edited … .” (Colin Griffin, RAD Magazine, May, 2021)
