Application Value of Ultrasonography in the Differential Diagnosis of Benign and Malignant Breast Nodules
Objective To study the application value of ultrasonography in the differential diagnosis of benign and malignant breast nodules.Methods Sixty patients with breast nodules diagnosed and treated in Yichun Xinjian Hospital from January 2021 to January 2023 were selected as the research objects.All patients were examined by ultrasonography.The imaging characteristics and blood flow parameters of benign and malignant lesions of breast nodules examined by ultrasonography[blood flow resistance index(RI),blood flow pulsation index(PI),peak flow velocity(Vmax)]were analyzed.The results of pathological examination were used as the gold standard to compare the value of ultrasonography in the differential diagnosis of benign and malignant breast nodules(diagnostic accuracy,sensitivity,specificity,positive predictive value,negative predictive value),and the detection rate of blood flow in benign and malignant breast nodules was counted.Results There was a statistically significant difference between the ultrasound signs of benign breast nodules and malignant nodules(P＜0.05).RI,PI and Vmax of malignant breast nodules were higher than those of benign breast nodules(P＜0.05).The diagnostic accuracy of ultrasound in differentiating benign and malignant breast nodules was 91.67％,the sensitivity was 94.29％,the specificity was 88.00％,the positive predictive value was 91.67％,and the negative predictive value was 91.67％.The detection rate of blood flow in malignant breast nodules by ultrasonography was 84.00％,which was higher than 62.86％in benign breast nodules(P＜0.05).Conclusion Ultrasonography has a high diagnostic efficiency in the differential diagnosis of benign and malignant breast nodules.It can provide reliable and rich differential basis through the characteristics of ultrasound signs,blood flow detection rate and quantitative parameters of blood flow,so as to improve the value of differential diagnosis.
