HNG DCIS lesion on (a, b) DCE and (c, d) DW (b = 600 sec/mm2) MR images in 37-year-old woman. (a) T1-weighted fat-suppressed image shows 51-mm mass. (b) The mass demonstrates 146% peak initial enhancement with areas of delayed washout (red), persistent (blue), and plateau (green) kinetic features. (c) The lesion demonstrated high signal intensity, with a calculated CNR of 2.35. (d) On ADC map the lesion demonstrates low signal intensity, with a mean ADC value of 1.45 × 10−3 mm2/sec.
