Small Lesions Evaluation Based on Unsupervised Cluster Analysis of Signal-Intensity Time Courses in Dynamic Breast MRI

Figure 6

Segmentation based on the “neural-gas” network applied to data set #1 (malignant lesion, ductal carcinoma in situ (DCIS)) and resulting in two clusters. (a) shows the cluster distribution for each slice ranging from 6 to 8. (b) visualizes the representative time-signal intensity time curves for each cluster.
