Heterogeneous Enhancement Pattern in DCE-MRI Reveals the Morphology of Normal Lymph Nodes: An Experimental Study

Figure 4

Enhancement pattern-based k-means clustering on 15 healthy nodes with Gd-DTPA (nodes #1–9) and with Gd-BOPTA (nodes #10–15). The red/green colours used to report the cluster-averaged NDE curves correspond to the colour used to localize them in the corresponding segmentation maps (on the right of each plot).
