Images obtained in a 49-year-old woman with invasive ductal carcinoma (estrogen receptor+/progesterone receptor+/human epidermal growth factor receptor 2-/Ki-67 > 20%) who was categorized in the non-pathologic complete response group. Shown from left to right are contrast-enhanced MRI images, diffusion-weighted (DW) MRI images (b = 1500 s/mm2), and color-coded quantitative DW MRI maps (overlaid on original DW images). Serial diffusion-related measures showed no obvious increase with treatment. For example, ADC200,1000 values were 0.86, 0.89 and 0.80 × 10–3 mm2/s, respectively, at pre-, mid-, and post-treatment
