The coronal plane of automatic breast volume scaner for modified BI?RADS classification of clinical study / 实用医学杂志

ABSTRACT

Objective To investigate the clinical value of modified BI?RADS classification by using the coronal plane of automatic breast volume scaner. Methods The total of 201 BI?RADS 3~5 classification of breast masses were retrospectively analyzed. All masses underwent conventional ultrasound and ABVS examination. Using BI? RADS classification standard terms to describe various information of breast masses, and record the coronal image of the masses on the complete interface echo, convergence sign, angle, burr, which classified BI?RADS ultimately. Results The coronal plane of convergence sign, complete interface echo, angulation and burr were significantly different between benign and malignant tumors (P<0.0001). The sensitivity of ABVS convergent sign in diagnosing breast malignant tumors was 68.2%, specificity was 93.4% and accuracy was 82%. The conventional ultrasound combined with the coronal feature of ABVS modified by BI?RADS classification showed that 3 kinds of malignant rate reduced from 8.5%to 3.2%. The rate of malignant 4a decreased from 25.2%to 12.1%and the rate of malignant 5 increased from 94.2% to 98%. Conclusion The convergence sign of ABVS can be used as a significant independent predictor of breast malignant tumors;ultrasound combined with ABVS is helpful to improve the accuracy of ultrasound BI?RADS classification.
