Abstract:
Objective To evaluate the value of supersonic shear wave elastrography(SWE) in the diagnosis of benign and malignant breast lesions.Methods SWE was performed on 134 breast lesions of 123 female patients and 74 normal breast glands to determine the values of overall elastic modulus and dispersion,and ROC curves were used to assess the diagnosis boundary value of two kinds of data respectively.Results According to the diagnostic gold standard-histopathology,the values of overall elastic modulus and dispersion were statistically significant when comparing benign lesions and malignant lesions with normal glands.ROC curve displayed that,when the Youden index reached to maximum,the diagnosis boundary value of overall elastic modulus was 41.01 kPa,the sensitivity and specificity of the value were 68.5％ and 83.8％ respectively; the diagnosis boundary value of dispersion was 12.25 kPa,the sensitivity and specificity of the value were 87.0％ and 88.7％ respectively.Conclusions The values of overall elastic modulus and dispersion for solid breast lesions can be used to reflect the elastic characteristics of lesions quantificationally,which is useful to diagnose benign and malignant breast lesions in clinical.
