Example for B-mode ultrasound and elastogram of a healthy, reactive LN. In B-mode ultrasound, the cortex of the LN is slightly enlarged (maximum ~3.5mm). The predominant color of the medulla is turquoise (to green) and the cortex is mainly green. Applying the criterion of a blue cortex, this case would be a true-negative.
