Objective To explore the application value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in diagnosing benign breast lesions and breast cancer.Methods A total of 289 patients with breast diseases treated at the Xichang People's Hospital from January 2021 to December 2023 were selected for this study.Using postoperative pathologi-cal results as the gold standard,the diagnostic value of DWI and DCE-MRI for benign breast lesions and breast cancer was analyzed,and the apparent diffusion coefficient(ADC)values and DCE-MRI imaging features of benign and malignant breast lesions were compared.Results Pathological results showed that among 289 breast disease patients,212 had benign lesions(73.36% )and 77 had breast cancer(26.64% ).Significant differences were found in ADC values,lesion margins,lesion shapes,TIC types,and enhancement characteristics between the benign and malignant groups(P＜0.05).DWI diag-nosed 188 cases of benign lesions and 101 cases of breast cancer with an accuracy rate of 72.66%;DCE-MRI diagnosed 179 cases of benign lesions and 110 cases of breast cancer with an accuracy rate of 66.44%;combined diagnosis yielded 203 cases of benign lesions and 86 cases of breast cancer with an accuracy rate of 87.54% (P＜0.05).The AUC for DWI,DCE-MRI,and the combined diagnosis was 0.871,0.806,and 0.911,respectively,with specificities of 92.21%,89.61%,and 90.91%,and sensitivities of 85.85%,80.66%,and 92.45%,respectively.Conclusion DWI and DCE-MRI have high clinical value in distinguishing between benign breast lesions and breast cancer,and their combination promotes diagnostic accuracy.
