The role of high frequency three-dimensional ultrasound coronal convergence sign in the diagnosis of breast masses

Abstract

Objective To explore the diagnostic value of high frequency three-dimensional (3D) ultrasound in breast masses. Methods Seventy-seven cases of breast lesions were selected by 2D ultrasonic scan, and all the cases had been examined by 3D ultrasound and accepted surgical treatment in Shenzhen People's Hospital. With pathological results as the gold standard for diagnosis, the convergence sign in diagnosis of breast masses was used as malignant standard for 3D ultrasound coronal plane. The sensitivity and specificity were analyzed of 3D ultrasound in the diagnosis of benign and malignant breast tumors. Results A total of 77 cases of breast lesions included 46 malignant and 31 benign. 3D ultrasound convergence sign was used to judge the benign and malignant breast tumors with statistical significance (χ2=26.790, P<0.01). The diagnostic sensitivity and specificity were 69.7%, and 90.3%, respectively. Conclusions High frequency 3D ultrasonography has certain value in differential diagnosis of benign and malignant breast tumors, and has important significance for the formulation of treatment plan.
