Guerbet Liver Fibrosis

Metabolic dysfunction-associated steatotic liver disease (MASLD, formerly known as nonalcoholic fatty liver disease or NAFLD) is characterized by the accumulation of excess fat in the liver, ranging from mild forms like non-alcoholic fatty liver (NAFL) to more severe stages such as metabolic dysfunction-associated steatohepatitis (MASH, formerly known as nonalcoholic steatohepatitis or NASH) with associated inflammation, ballooning, fibrosis, and cirrhosis. The severity of MASH and increasing fibrosis stages is associated with higher morbidity and mortality rates. The study will compare dynamic contrast-enhanced (DCE)-MRI measurements of perfusion using gadopiclenol for diagnosis of liver fibrosis to MR elastography and transient elastography, T1 mapping, ultrasound elastography and blood tests, using histopathology as the reference in patients with MASH. In this study, the value of DCE-MRI and texture analysis using gadopiclenol, a new macrocyclic, non-ionic, extracellular contrast agent with high relaxivity will also be assessed which provides, at a lower dose, better contrast-to-noise ratio than gadoterate, gadobenate, and gadobutrol.
