Assessment of Metastatic Breast Cancer Response to Chemoembolization with Contrast Agent-enhanced and Diffusion-weighted MR Imaging

In patients with breast cancer and liver metastases who were treated with TACE, although changes in tumor size were small, significant early changes in the treated lesions occurred on contrast medium-enhanced and functional MR imaging. These include decrease in tumor enhancement and increase in tumor ADC value, which suggest increasing tumor necrosis and cell death.
