The proximal locations of the liver and pancreas in the abdomen make it tempting to report the PDFF of both in a single scan. However, published methods for liver fat measurement need revision before they accurately measure pancreatic fat. UK Biobank scans were used to quantify the quality of fits of a method developed previously for liver PDFF when applied to the pancreas. Pancreas fits were an order of magnitude lower than fits in the liver or the spleen. This could be due to a suboptimal acquisition or because the liver fat model does not approximate well to the pancreas.
