Fig. 3

A and B, Drawing (A) and axillary US image (B) representing type I morphologic classification of normal node. Hyperechoic hilum is visible, and there is almost no visible cortex.

C and D, Drawing (C) and axillary US image (D) representing type II morphologic classification of normal node. Hyperechoic hilum is visible, and there is thin (≤ 3 mm) hypoechoic cortex.

E and F, Drawing (E) and axillary US image (F) representing type III morphologic classification of abnormal node. Hyperechoic hilum is visible, and hypoechoic cortex is thicker than 3 mm.

G and H, Drawing (G) and axillary US image (H) representing type IV morphologic classification of abnormal node. Hyperechoic hilum is visible but is effaced, and there is generalized lobulated hypoechoic cortex.

I and J, Drawing (I) and axillary US image (J) representing type V morphologic classification of abnormal node. Hyperechoic hilum is visible, and there is focal hypoechoic cortical lobulation.

K and L, Drawing (K) and axillary US image (L) representing type VI morphologic classification of abnormal node. No hilum is visible, and the node is totally hypoechoic.
