Value of contrast-enhanced ultrasound combined with elastography in evaluating cervical lymph node metastasis in papillary thyroid carcinoma

Figure 1 Ultrasound contrast sonogram of metastatic lymph nodes. It reveals that the lymph nodes were enhanced, and the distribution was not uniform.

Figure 2 Elastography of metastatic lymph nodes in papillary thyroid carcinoma. It reveals that the lymph nodes had a hard texture and blue-green color.
