- Abstract: Objective To evaluate the diagnostic efficacy of the Kaiser score for ultrasound(US)BI-RADS 4A lesions and the potential to avoid unnecessary biopsies.Methods Data of patients who underwent breast US and magnetic resonance imaging(MRI)between May 2019 and June 2023 were retrospectively collected,and all cases were confirmed by puncture biopsy or surgical pathology.The diagnostic efficacy of Kaiser score and MRI BI-RADS classification for US BI-RADS 4A lesions was calculated and compared using pathologic findings as the gold standard.Results A total of 119 lesions(74 benign and 45 malignant lesions)were found in the 119 patients.The diagnostic efficacy of the Kaiser score was significantly better than that of the MRI BI-RADS classification(AUC:0.88 vs.0.65,P＜0.000 1).The concordance of the Kaiser score results with the pathologic findings and the inter-observer concordance were better than that of the MRI BI-RADS classification.Unnecessary biopsies could be avoided in 87.8％(65/74)and 33.8％(25/74)of the cases when the Kaiser score and the MRI BI-RADS classification were applied for the diagnosis of US BI-RADS 4A lesions,respectively.Conclusion The Kaiser score can provide a diagnostic basis for risk stratification of US BI-RADS 4A lesions,and its diagnostic efficacy and inter-observer agreement are superior to those of MRI BI-RADS classification.
