  		Figure 1a. Images in 69-year-old man with NSCLC. (a) Transverse US image of right supraclavicular region shows hypoechoic round enlarged nonpalpable lymph node (in crosshairs). Cytologic examination revealed metastasis. (b) Coronal reconstructed contrast material-enhanced CT scan shows the enlarged hypoattenuating lymph node with metastasis (arrow) in the right supraclavicular fossa.

  		Figure 2. Relationship between diameter of supraclavicular lymph nodes with metastasis and their chance of palpability. To have a 50% chance of being palpable, nodes had to have a diameter of at least 22.3 mm (95% CI: 17.2, {infty} mm).
