The objective is to develop a novel multiparametric ultrasound-based technique to quantify the amount of steatosis in the liver by using the current MRI-based gold-standard - MRI proton density fat fraction (MRI-PDFF) as a clinical reference. This clinical development study will only collect the required dataset from healthy volunteers and subjects with different degrees of steatosis in the liver, particularly patients with MASLD, formerly non-alcoholic fatty liver disease (NAFLD). It will capture the raw radiofrequency data required for the development of this new radiologic biomarker on a research ultrasound imaging device. In addition, various other clinical and radiological datasets will be captured to support the ground truthing, development and training of the novel ultrasound-based multiparametric biomarker.
