ARTICLE HIGHLIGHTS
Research background
Shear wave elastography can help the differential diagnosis of breast lesions by evaluating the hardness of breast lesions; however, there are few studies on the evaluation of the elasticity of breast non-mass lesions. In recent years, studies have shown that the evaluation of peripheral elasticity of breast lesions may have better diagnostic efficacy than other parameters. However, there has been no study on the internal and peripheral elasticity of breast non-mass lesions.
Research motivation
The aim of this study was to evaluate the internal and peripheral elasticity of breast non-mass lesions using shear wave elastography.
Research objectives
To determine the value of shear wave elastography in the differential diagnosis of non-mass breast lesions.
Research methods
The peripheral (the shell of 1 mm, 1.5 mm, 2 mm, 2.5 mm and 3 mm around the lesions) and internal elasticity of non-mass breast lesions in 118 cases were evaluated. ROC curves of each parameter were drawn and the diagnostic efficacy of each parameter was compared.
Research results
The “stiff rim” sign and other quantitative parameters within and around the breast NMLs had good diagnostic efficiency. Emax of peripheral shells had better evaluation efficiency.
Research conclusions
Combining qualitative and quantitative analyses of both internal and shell stiffness may further improve the diagnostic efficiency of breast non-mass lesions.
Research perspectives
In this study, we focused on the influence of the stiffness of the peripheral shell in breast non-mass lesions on diagnosis.
