Example for B-mode ultrasound and elastogram of a metastatic LN. In B-mode ultrasound, the cortex of the LN is slightly enlarged (maximum ~3.0mm). The predominant color of the medulla is turquoise and cortex is mainly blue. Applying the criterion of a blue cortex, this case would be a true-positive.
