Figure 1

Component planes with a SOM for CE-T1WI, FLAIR, MTRasym at 3.0 ppm, and ADC colorized from blue to red according to each value, with red indicating a higher weight. The inter-class borderlines obtained by K-means clustering with K = 10 are shown on the SOM component planes as black lines between the nodes. Detailed profiles can be seen on the K-means clustering map from labels 1 to 10 shown at the far right.
