Value of DCE-MRI Combined with T2WI and DWI in the Diagnosis of Breast Cancer
Objective To evaluate the value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)combined with T2-weighted imaging(T2WI)and diffusion-weighted imaging(DWI)in the diagnosis of breast cancer(BC).Methods A retrospective collection was performed on the clinical data of 78 patients with breast lesions in the hospital between April 2021 and April 2023.All patients underwent DCE-MRI,T2WI and DWI scans after admission,and the examination results were statistically analyzed.The imaging characteristics of benign and malignant breast lesions were analyzed.Taking surgical pathology as the golden standard,the value of DCE-MRI combined with T2WI and DWI in the diagnosis of BC was analyzed.Results:Among the 78 patients with breast lesions(90 lesions),there were 26 cases with benign lesions(31 lesions)and 52 cases with malignant lesions(59 lesions).The main benign lesion was fibroadenoma[38.71％(12/31)],while the main malignant lesion was invasive ductal carcinoma[40.68％(24/59)].There were significant differences in imaging characteristics(margin,enhancement characteristics,T2WI findings)between benign and malignant breast lesions(P＜0.05).DCE-MRI showed that there were 71 malignant lesions and 19 benign lesions,T2WI showed that there were 62 malignant lesions and 28 benign lesions,DWI showed that there were 66 malignant lesions and 24 benign lesions,and combined detection showed that there were 47 malignant lesions and 43 benign lesions.Taking pathological results as the golden standard,the sensitivity,specificity and accuracy of DCE-MRI,T2WI,DWI and combined detection in the diagnosis of malignant breast lesions were(86.44％,35.48％,68.89％),(77.97％,48.39％,67.78％),(79.66％,38.71％,65.56％)and(76.27％,93.55％,82.22％),respectively.The specificity and accuracy of combined detection were higher than those of single index(P＜0.05).Conclusion DCE-MRI,T2WI and DWI all have certain value in the diagnosis of BC,and the diagnostic value of combined detection is higher.
