Abstract
This study aimed to evaluate the diagnostic accuracy of strain and shear wave elastography compared to conventional ultrasonography in differentiating between benign and malignant lymphadenopathy.
We found statistically significant differences for the following criteria in a total of 60 patients: short axis, long axis/short axis ratio, cortical asymmetry, thickness, lost hilum, strain ratio, strain score, intranodal kpa or velocity, and elasticity ratio.
The elasticity ratio had the best accuracy (88.9%), followed by the strain ratio (83.8%), and then intra-nodal kpa or velocity (79% accuracy). Cortical asymmetry achieved 100% sensitivity, followed by strain ratio and elasticity ratio (90% and 87.5%, respectively). The elasticity ratio (80%) had the best specificity, followed by the strain score (75%) and the strain ratio (70%). In conclusion, cortical asymmetry had the best sensitivity but the lowest specificity (25%), whereas the elasticity ratio had the highest accuracy (88.9%) and specificity (80%).
