The Research Of Ultrasound Elastography Technology And "Firefly" Technology In Breast Benign And Malignant Lesions Diagnosis

Objective:To analyze real-time ultrasound elastography strain rate ratio as a whole and the local strain rate ratio best critical value of diagnosis of benign and malignant breast lesions and to compare real-time ultrasound elastography strain rate ratio(ESR)as a whole with the diagnostic value of local strain rate ratio(LSR).Meanwhile,compared with ultrasonic firefly technology diagnosis and then discuss the value and significance of ultrasonic firefly technology combine real-time ultrasound elastography in the diagnosis of benign and malignant breast lesions in order to provide reference and help for Improving ultrasound in differential diagnosis of benign and malignant breast lesions.Methods:Choose 94 cases of female patients with breast lumps as the research object from June 2015 to June 2016.The pathology diagnosed104 breast lesions,which consisted of 74 benign lesions and 30 malignant lesions.Preoperative patients adopt Toshiba Aplio500 color doppler ultrasonic detector with real-time ultrasound elastography respectively and "fireflies" technical examination of the lesion,With pathologic results as the gold standard,ROC curve drawing.At the same time,diagnose the results of benign and malignant breast lesions according to the Area under the Curve(Area under the ROC Curve,AUC)compare local strain rate ratio and the strain rate ratio as a whole.Take pathologic results as the gold standard,adopt "fireflies" technology,real-time ultrasound elasticity imaging(Ultrasonic elastography,UE)respectively and two kinds of joint detection technology inspection on breast lumps to compare the accuracy,specificity and sensitivity of different ways in the diagnosis of benign and malignant breast lesions.Results:Benign lesions of local strain rate ratio and the strain rate ratio than malignant lesions,comparative differences are statistically significant(P < 0.05).Local strain rate ratio and the strain rate ratio of AUC are 0.92 and 0.85 respectively,the best point of 31.14 and 31.14,both the sensitivity of the diagnosis of benign and malignant breast lesions,specific degrees and accuracy were 84.6%,80.0%,86.5% and84.6% 63.3%,71.6% respectively.The local strain rate ratio value to the diagnosis of benign and malignant breast lesions is better than that of the overall strain rate ratio,which was statistically difference(P < 0.05).Ultrasonic "fireflies" technology and real-time elastography in the diagnosis of benign and malignant lesions of accuracy and sensitivity,specific degrees were 86.5%,80.0%,89.2% and 86.5% respectively,76.7%,87.8%,both joint detection accuracy and sensitivity,specific degrees are 96.2%,93.3% and 96.2% respectively;Joint detection accuracy,sensitivity and ultrasonic "fireflies" technology and real-time elastography in the diagnosis of compared statistically difference(P <0.05),the highest sensitivity of joint detection,but with ultrasonic "fireflies" technology and real-time elastography detection sensitivity had no statistical difference(P > 0.05).Conclusions:Both Real-time ultrasound elastography strain rate ratio as a whole and local strain rate ratio has important diagnostic value for benign and malignant breast lesions and the latter is higher,better than the overall diagnostic value of the strain rate ratio;Combination of real-time ultrasound elasticity imaging and "fireflies" technology for diagnosis of benign and malignant breast lesions.The accuracy,sensitivity and specific degrees has improved obviously,which has high diagnostic value as well.
