Abstract:
Objective:To explore the differential diagnostic value of ultrasonic elastography for breast nodules with acoustic attenuation.Methods:A total of 105 cases with breast nodules with posterior echo attenuation from June 2017 to October 2019 in Shenzhen People′s Hospital were enrolled. Routine ultrasound examination and elastography were performed and maximum of elastography(Emax), mean of elastography value(Emean), minimum of elastography value(Emin) and strain ratio of fat/strain ratio of nodules(B/A) were recorded. With the pathological results as the diagnosed gold standard, elastic parameters different between benign and malignant breast nodules with posterior echo attenuation were compared. And the Emax value of elastic imaging was analyzed by the ROC curve.Results:There were 65 cases of benign nodules and 40 cases of malignancy. The difference of ultrasound E imaging were statistically significant for judging benign and malignant breast nodules with acoustic attenuation( P<0.05). When Emax 95 kPa was set as the cut-off value for the differential diagnosis of benign and malignat breast nodules, the area under the ROC curve was 0.817, and the sensitivity was 88% and the specificity was 72%. Conclusions:Ultrasonic elastrography is of great value for differential diagnosis of benign and malignant breast nodules with acoustic attenuation, and it is important for the decision making of clinical treatment plan.
