Abstract：Objective: To investigate the application value of DCE-MRI and DWI in the diagnosis of breast cancer. Methods: A total of 78 cases of breast cancer patients were selected from January 2015 to October 2015 in our hospital and were identified as breast cancer. The diagnostic efficacy of DCE-MRI, DWI and the combination of the two methods were compared. Results: Fifty-three malignant lesions and 30 benign lesions were confirmed by histopathology. Sixty-four malignant lesions and 19 benign lesions were detected by DCE-MRI, sensitivity 94.3%, specificity 53.3%, accuracy 79.5%, positive predictive value 78.1%, positive likelihood ratio 2.02, negative predictive value 84.2%, negative likelihood ratio 0.11, Youden index 0.476. Sixty-one malignant lesions and 22 benign lesions were detected by DWI, sensitivity 94.3%, specificity 63.3%, accuracy 83.1%, positive predictive value 82.0%, positive likelihood ratio 2.59, negative predictive value 86.4%, negative likelihood ratio 0.09, Youden index 0.728. Fifty-four malignant lesions and 29 benign lesions were detected combined DCE-MRI with DWI, sensitivity 96.2%, specificity 90.0%, accuracy 94.0%, positive predictive value 94.4%, positive likelihood ratio 9.62, negative predictive value 93.1%, negative likelihood ratio 0.04, Youden index 0.862. The application value of combined method was better than DCE-MRI and DWI. Conclusion: DCE-MRI combined with DWI can significantly improve the diagnostic efficacy of breast cancer.
