Research Focus

Dr. Rettenmeier is interested in the development of new imaging techniques and their application in disease. His major clinical focus is on the characterization of liver tissue in the context of metabolic liver disease as one of the leading causes of cirrhosis and cancer. He is involved in several research projects involving different medical imaging modalities, but his primary research focus is on the development of methods using Magnetic Resonance Imaging (MRI). Dr. Rettenmeier’s MRI projects cover structural and functional methodologies in brain and body and include the design of MR pulse sequences and model-based image reconstruction techniques. He is particularly interested in abdominal imaging techniques that enable the quantitative mapping of multiple MR parameters.
