Figure 4.

3D volume-rendered image of a tube associated with multiple islets surrounded by acinar cells. Through manipulation of the opacity of the 3D volume image, different tissue components of the pancreas can be highlighted based on differences in magnetic resonance signal intensity, as reflected by the color scale (green to red, low to high intensity). Several notable structures can be observed: the high intensity of a lumen within a tube (A); the wall of the tube shown in A, with adjacent islets that have similar signal intensity (B); a tube and islets, with heterogeneous intensity visible within the islets (C); and islets and tubes as they appear in the tissue, surrounded by acinar cells (D). When their opacity is reduced, acinar cells appear translucent, allowing improved visualization of the islets and tube.
