Abstract

Abstract:
Background:
Sonoelastography is a novel technology that relies on the elastic properties of soft tissues, with the premise that malignant lesions are stiffer than benign or normal tissue. It may have a promising role in detecting malignant salivary gland lesions, in the same manner as it has been applied to different parts of the body, such as the breast.
Imaging is required to diagnose the salivary gland diseases, which range from mild inflammatory conditions to a group of benign and malignant neoplasms, as physical examinations and laboratory tests alone are insufficient to distinguish between these diseases. Also, conventional imaging modalities are inconclusive in differentiating between benign and malignant lesions because of the significant overlap between their imaging features.
Results: The study included 34 patients with salivary gland lesions. By comparing the sonoelastography features between patients with malignant versus those with benign lesions, we observed that mean shear moduli and strain ratio were significantly higher in malignant lesions than in benign ones [P < 0.05].
Also, the elasticity score was completely blue in malignant lesions, whereas no cases with benign lesions showed a blue color when measuring the elasticity score.
Conclusion: Sonoelastography is reliable in assessing major salivary gland lesions and detecting malignant ones.
