Purpose: This study aimed to evaluate the difference in dynamic contrast enhanced magnetic resonance imaging characteristics between low-risk and non-low-risk breast cancers and to explore the possible pathological basis.
Materials and methods: Approval from the institutional review board and informed consent were acquired for this study. The MR images of 104 lesions with pathologically proven breast cancer were retrospectively analyzed.
Result: Low-risk tumors showed significantly lower Ktrans and Kep values and higher ADC value than non-low-risk breast cancers.
Conclusion: The prediction parameter using Ktrans, Kep, and ADC obtained on DCE-MRI and diffusion-weighted imaging could facilitate the identification of low-risk breast cancers.
