[Abstract] Objective: To evaluate the different diagnostic value in breast lesions, especially breast cancer, by dynamic contrast enhanced MR imaging, mammography, and ultrasonic.Materials and Methods: Thirty patients with 61 breast lesions were studied by dynamic contrast MRI, mammography, and ultrasonic independently before operation. The diagnostic sensitivity and specificity of each imaging modality were calculated independently and compared among each modality.Results: The diagnostic sensitivity and specificity of ultrasound, mammography and contrast enhanced MR imaging were 41.2 %, 84.6 %; 35.3 %, 87.2 %; and 94.1 %, 94.9 %, respectively. There was significant difference on diagnostic accuracy in MR and mammography (χ2=32.378, P=0.000). Ultrasound and mammography showed no diagnostic difference (χ2=0.569, P=0.451).Conclusion: Dynamic contrast enhanced MRI is a more effective diagnostic method in the diagnosis of breast diseases than mammography and ultrasonic.
