Progress of magnetic resonance imaging in efficacy evaluation of neoadjuvant chemotherapy in breast cancer

Neoadjuvant chemotherapy (NAC) is one of the important treatment strategies for breast cancer, which can lower the clinical stage and facilitate breast conserving surgery. Evaluating the effect of NAC accurately by using image technology plays a key role. Magnetic resonance imaging (MRI) is an assessment technique with high susceptibility and sensitivity, which can not only evaluate the effect from morphology, but can provide timely and useful information in the efficacy evaluation of NAC in breast cancer through diffusion-weighted imaging (DWI), dynamic contrast enhanced MRI (DCE-MRI), perfusion-weighted imaging (PWI).
