Colour map of pancreatic fat distribution in type 2 diabetes.

<p>The colour map shows the wide range of fat distribution within the sampling area. This underlies the rationale for thresholding to exclude non-parenchymal tissues. The colour bar on the right shows fat level from 0% (dark blue) to 25% (red). Threshold levels were set to exclude areas of fat content less than 1% (possible blood vessels or main duct) or above 20% (visceral fat contamination). Parenchymal fat was considered to range between 1–20%. a1-a6 represent areas of varied fat content within the single MR-opsy selection (a1: < 1%, a2: 1–5%, a3:6–10%, a4:11–15%, a5:16–20%, a6: > 20%).</p>
