  1. The coefficients for all organs of the native and the contrast-enhanced datasets are depicted to assess the quality of two organ segmentations by manual delineation. Furthermore, the calculated standard deviation (Std dev) and the minimum and maximum values of the Sørensen–Dice coefficient are shown. The main difference between the native and the contrast-enhanced μCT data is the increase in Sørensen–Dice coefficient showing the higher similarity in segmentation of the spleen (increase from 0.373 to 0.820, as highlighted with *). The data are also graphically depicted in Fig. 3.
