Research on metabolic dysfunction-associated steatotic liver disease (MASLD)

MASLD has become the most common liver disease affecting adults and children.

Our research purposes are to further characterize the natural history of MASLD, identify factors that influence the progression of MASLD, and to develop and validate diagnostic methods for MASLD.

Liver examinations without needles

How is your liver doing? Decades of research into the use of magnet resonance imaging is now being put to work to gain information about patients’ livers – without needles.

European project to develop better tests for liver disease

A large European research project aims to develop better diagnostics to predict which patients with non-alcoholic fatty liver disease run the highest risk of developing severe disease.

Magnetic resonance finds fatty liver

Taking tissue samples to diagnose fatty liver can be replaced in most cases by a painless magnetic resonance investigation, according to a new study.
