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

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.

Automated breast volume imaging with color doppler ultrasound in evaluating effect of neoadjuvant chemotherapy for breast cancer / 中国肿瘤临床

Objective: To explore automatic breast full volume imaging (ABVS) and color doppler ultrasound (CDFI) for breast cancer neoadjuvant chemotherapy (NCT) in the evaluation of curative effect. Methods:The application of a CDFI and ABVS 42 cases of breast cancer patients receiving NCT lesions imaging characteristics before and after observation and analysis. Results:ABVS from coronal distribution and audio-visual change according to the primary tumor, and CDFI images showing the primary tumors and blood flow changes within all have significant difference in patients with complete remission after NCT (P0.05). Conclusion:We use ABVS and CDFI for breast cancer before and after the NCT curative effect evaluation of great clinical significance and value.
