Ultrasound (US) elastography has been introduced as a noninvasive imaging
technique for evaluating cervical lymph nodes. US elastography techniques include
strain elastography and shear wave-based elastography. The application of this
technique is based on the fact that stiff tissues tend to deform less and show
less strain than compliant tissues when the same force is applied. In general,
metastatic lymph nodes demonstrate higher stiffness than benign lymph nodes.
Overall, preliminary studies suggest that US elastography may be useful in
differentiating benign and malignant cervical lymph nodes, thereby informing
decisions to perform a biopsy and facilitating follow-up. For US elastography to
be accepted into clinical practice, however, its techniques, associated
diagnostic criteria, and reliability need to be further refined.
