Example of a CCRG segmentation leaking out of the lymph node at a certain (unpredictable) value of b.
Segmentation results of three example lymph nodes. For each node, a coronal, sagittal, and axial slice through the seed point are shown. Lymph node A is segmented well by all four automated segmentation methods. Leakage out of lymph nodes B and C is seen in the segmentations by the CCRG and GCS methods, respectively. Note that, while in these 2-D slices, some leaked-into regions seem disjoint, they are connected in the 3-D image.
ROC curves of all segmentation methods.
The effect on the diagnostic accuracy of the normal vs metastasis classification using six types of segmentation. Error bars represent 95% confidence intervals.
Summary statistics (minimum, first quartile, median, mean, third quartile, and maximum) for the segmentation performance in terms of DSC and JI.
