Diagnostic Value of Strain Elastography and Color Doppler Techniques for Non-mass-type Lesions of the Breast Diagnosed by Two-dimensional Ultrasound
Objective:To investigate the diagnostic value of strain elastography(SE)and color Dop-pler Flow Image(CDFI)for non-mass-like lesions(NML)diagnosed by two-dimensional ultrasound(2D US).The diagnostic value of two-dimensional ultrasound(2D US)in the diagnosis of non-mass-like le-sions(NML)in the breast,and to improve the detection rate of non-mass-like lesions in the breast.Meth-ods:102 cases of non-mass-like lesions diagnosed by 2D US,CDFI and SE and confirmed by pathology were retrospectively analyzed,and the diagnostic efficacies of 2D US,CDFI and SE were calculated to dif-ferentiate the benignness and malignancy of non-mass-like lesions.Results:Among the 102 cases,46 were benign and 56 were malignant.2D US had a diagnostic sensitivity of 75.00％,a specificity of 56.67％,an accuracy of 66.7％,and an AUC of 0.662.SE had a diagnostic sensitivity of 86.11％,a speci-ficity of 83.33％,an accuracy of 84.85％,and an AUC of 0.902.CDFI had a diagnostic sensitivity of 80.56％,a specificity of 66.67％,an accuracy of 74.24％,and an AUC of 0.828.2D US+SE+CDFI diag-nostic had a sensitivity of 91.67％,a specificity of 90.00％,an accuracy of 90.91％,and an AUC of 0.974.Conclusion:2D US in combination with SE and CDFI can increase the diagnostic value of non-mass-type lesions of the breast,and can help to predict non-mass-type breast malignant lesions.
