Abstract:

Objective　To investigate the value of automated breast ultrasound (ABUS) in the diagnosis of 4A benign and malignant breast nodules in the breast imaging reporting and data system (BI-RADS). Methods　Two hundred and two female patients with a total of 216 BI-RADS 4A breast nodules [the longest diameter was (17.92±11.60) mm] found by ABUS in Guangdong Provincial Hospital of Chinese Medicine from January 2018 to September 2022 were retrospectively analyzed; they were 23-72 years old. All the patients were examined by ABUS, conventional ultrasound, and mammography. The BI-RADS classification was conducted according to the classification standard of Breast Imaging Report and Data System established by the American College of Radiology (ACR) in 2013. The postoperative pathological results were used as the gold standard to analyze the diagnostic efficacies of the three methods. The χ² test or Fisher's exact probability method were used to compare the count data. Results　It was confirmed by surgery and pathology that 178 nodules were benign, and 38 malignant. The malignant composition ratios of B-RADS 4A breast nodules by ABUS, routine ultrasound, and mammography were 17.59% (38/216), 12.94% (22/170), and 19.61% (10/51), respectively. There were no statistical differences between the three groups in the malignant composition ratio of BI-RADS 4A nodules between by ABUS and by conventional ultrasound, between by ABUS and by mammography, and between by conventional ultrasound and by mammography (χ²=1.568, 0.114, and 1.408; all P>0.05). Conclusions　The diagnostic efficacy of ABUS for BI-RADS 4A breast nodules is similar to those of conventional ultrasound and mammography. ABUS has certain clinical value in early breast cancer screening, and is conducive to breast disease screening and disease grading management in grass-root units.
