The role of Sonoelastography in the assessment of enlarged cervical lymph nodes and salivary gland tumors

Purpose: Sonoelastography is a non-invasive method of medical imaging technique which measures stiffness of tissue to detect or classify reactive and metastatic lymphadenopathy. The principle underlying sonoelastography is that tissue compression produces displacement within the tissue, which is usually different in tumor tissues than in normal surrounding tissue. The deformation measurements are mapped onto an elastogram (images of tissue strain), on which stiffer areas are depicted in colour as blue and more-elastic areas are red, according to convention. Sonoelastography has shown reliable results for cancers…
