Objective To investigate the application of mammography combined with conventional magnetic resonance imaging(MRI)sequences and diffusion weighted imaging(DWI)sequences in the diagnosis of breast cancer.Methods The clinical data of 80 patients with breast lesions admitted to the hospital from February 2021 to February 2023 were analyzed retrospectively.All patients underwent mammography and MRI examination.Pathological results were taken as the golden standard to analyze the diagnostic performance of the two methods and their combination.The mammography and MRI features of different lesions were analyzed.Results Pathological results confirmed 36 cases of benign lesions and 44 cases of breast cancer.The sensitivity,specificity and accuracy of mammography,MRI,and their combination were(88.89％,79.55％and 83.75％),(94.44％,86.36％and 90.00％),and(97.22％,95.45％and 95.25％),respectively.The proportions of MRI signs(irregular margin,lobulated shape,inhomogeneous enhancement and outflow type TIC)in breast cancer were higher than those in benign lesions,and the ADC value was lower than that of benign lesions(P＜0.05).Conclusion Mammography combined with conventional MRI sequence and DWI sequence is relatively accurate in diagnosing breast cancer.
