Abstract:
Objective To investigate two-dimensional color Doppler commissure real-time shear wave elastrography (SWE) examination and its application value in the diagnosis of breast diseases.Methods One hundred and thirty patients (158 breast lesions) confirmed with breast disease were chosen from September 2013 to September 2014,and all patients underwent two-dimensional color Doppler ultrasound and SWE examination.The receiver operating characteristic (ROC) curve was examined to obtain maximum elasticity modulus value,average elastic modulus value and the corresponding critical value for the diagnosis of benign and malignant breast lesions.According to the results of pathological examination,sensitivity,specificity and accuracy of two-dimensional ultrasound and SWE for the diagnosis of breast lesions were evaluated and compared.Results Of all 158 breast lesions in 130 patients,90 were malignant lesions and 68 were benign lesions.The sensitivities of two-dimensional ultrasound and SWE in diagnosis of breast cancer were 89.7％ and 89.5％,the specificities were 85.6％ and 95.3％ and the accuracy were 87.3％ and 91.4％,respectively.The sensitivity,specificity and accuracy in the diagnosis of breast cancer by combination of two-dimensional ultrasound and SWE were 98.5％,93.3％,95.6％,respectively.Conclusions Although two-dimensional color Doppler ultrasound is a commonly used method in the diagnosis of breast lesions,it has certain limitation.The specificity of diagnosis can be improved by SWE,which is a useful complement to traditional two-dimensional ultrasound technology.Combination of the two methods can significantly increase the sensitivity and accuracy of the diagnosis and provide a reliable basis for the differential diagnosis,reduce the rate of misdiagnosis,missed diagnosis and unnecessary biopsy,which has important clinical application value.
