Value of breast imaging reporting and data system in the diagnosis of benign and malignant breast lesions
Objective To explore the value of ultrasound breast imaging reporting and data system(BI-RADS)in the diag-nosis of benign and malignant breast lesions.Methods Retrospective analysis was conducted on clinical data from 107 pa-tients who underwent surgical resection of breast tumors and corresponding pathological examinations at Jiyuan Maternal and Child Health Hospital from January 1,2020 to June 1,2023.All patients underwent ultrasound examination and BI-RADS was used to identify the benign and malignant nature.The results of surgical pathological cytology examination were used as the gold standard to compare the diagnostic efficacy of BI-RADS score with the gold standard.Then,ac-cording to the BI-RADS score,the ultrasonic signs and blood flow characteristics of benign and malignant tumors were analyzed.Results Among 107 patients with breast tumor,36(33.64％)were diagnosed as malignant and 71(66.36％)as benign through surgical pathology examination;The BI-RADS score detected 69 cases of benign(64.48％)and 38 ca-ses of malignant(35.52％);Among 107 cases of breast lesions,the sensitivity,accuracy,and specificity of BI-RADS score in diagnosing breast tumor patients were 94.44％,94.39％,and 94.37％,respectively,which were consistent with the gold standard(Kappa=0.876);There were statistically significant differences in morphology(x2=14.076,P＜0.001),aspect ratio(x2=37.905,P＜0.001),margin(x2=34.845,P＜0.001),calcification(x2=21.953,P＜0.001),boundary(x2=34.810,P＜0.001),posterior echo(x2=22.178,P＜0.001),and changes in surrounding tis-sue(x2=48.937,P＜0.001)between benign and malignant lesions,but there was no statistically significant difference in blood flow characteristics(x2=0.787,P=0.375)and changes in internal echo(x2=1.848,P=0.605).Conclusion The BI-RADS system can effectively distinguish the image signs of benign and malignant breast lesions,improve the detection rate of ma-lignant tumors,and have high diagnostic value.
