Figure 1: MR images of representative cases. (a) Case 3: a 59-year-old woman with invasive carcinoma of the left breast. E/D ratio: 1.03, ADC value 0.850 × 10-3 mm2/s. A well-demarcated mass with strong enhancement is observed. The mass shows high intensity on DWI (b = 1000). (b) Case 13: a 72-year-old woman with invasive carcinoma in the right breast. E/D ratio: 0.90, ADC value 0.975 × 10-3 mm2/s. A mass with early rim enhancement with delayed internal enhancement is shown. The mass shows high intensity on DWI (b = 1000). The central portion shows relatively low signal intensity than that in the periphery. The central area showing delayed enhancement may have abundant fibrous stroma.
