Ultrasound type

Color Doppler

1. Marginal blood flow

2. Heart-shaped blood flow

1. Hilus blood flow

2. No blood flow

Elastography

1. Red or yellow-green (type I)

1. Blue > 45% (type III)

2. Blue in the peripheral zone and red or yellow-green in the center (type IV)

3. Blue throughout most of the lymph node (type V)

Contrast-enhanced ultrasound

1. Marginal enhancement
