Fig 1 Image characteristics of metastatic and reactive lymph nodes and representative morphologic findings of endobronchial ultrasonography images used for classifying metastatic and reactive lymph nodes: size; long axis greater than 1.67 cm and short axis 1.42 cm or less; shape, oval or round; margin, indistinct (arrow) or distinct; central hilar structure, present or absent; echogenicity, homogeneous or heterogeneous; necrosis sign, present (arrow) or absent; matting, present (arrow) or absent; calcification, present (arrow) or absent; vascular patterns, avascular, hilar, or nonhilar (capsular, central, mixed).

Fig 2 Receiver-operating characteristic curve analysis for short-axis diameter (cm) lymph node. A short-axis diameter threshold of 1.42 cm is the cutoff defined for predicting lymph node metastasis. Solid line indicates sensitivity; broken line indicates specificity.

Fig 3 Receiver-operating characteristic curve analysis for long-axis diameter (cm) lymph node. A long-axis diameter threshold of 1.67 cm is the cutoff defined for predicting lymph node metastasis. Solid line indicates sensitivity; broken line indicates specificity.

Fig 4 Endobronchial ultrasonography image classification and final confirmation, including pathology and at least 24 months of clinical follow-up, for metastatic lymph nodes (shaded bar) and reactive lymph nodes (open bar). (CHS = central hilar structure; NS = necrosis sign.)

Fig 5 Endobronchial ultrasonography images for reactive and metastatic nodes. Typical reactive lymph nodes: (A) absence of matting, presence of CHS; (B) hilar vascular pattern perfusion. Typical metastatic lymph nodes: (C) round shape, presence of matting, absence of CHS; (D) nonhilar vascular pattern perfusion.
