Figure 3: A comparison of elastography in malignant- and benign-looking lymph nodes in mediastinum. (a) A rounded lymph node. (b) Qualitative elastography shows a high strain ratio of 77. (c) Conglomerated lymph nodes. (d) The conglomerated node shows heterogeneous appearance with blue areas mixed with green areas, and even the strain ratio is high. The heterogeneity suggests a nonmalignant lesion, and fine-needle aspiration cytology reveals a tubercular lymph node
