A 38-year-old woman with dense breasts, with pathologically proven invasive carcinoma of no special type and mucinous carcinoma in the right breast. The lesion visibility scores of MG, DWI + TIRM, and clinical MRI of the lesion (arrow) were 4, 5, and 5, respectively. The breast cancer detection scores of MG, DWI + TIRM, and clinical MRI of the lesion (arrow) were 3, 4, and 5, respectively. The lesion visibility scores of MG, DWI + TIRM, and clinical MRI of the lesion (arrow head) were 2, 5, and 5, respectively. The breast cancer detection scores of MG, DWI + TIRM, and clinical MRI of the lesion (arrow head) were 2, 4, and 5, respectively. a MG showed a high-density lesion with a circumscribed margin. b TIRM and c DWI (b = 0.8 × 10−3 s/mm2) demonstrated a heterogeneous high-signal-intensity lesion (arrow) and a homogeneous high-signal-intensity lesion (arrow head) in the right breast. d ADC values of these two lesions were 0.78 × 10−3 mm2/s (arrow) and 0.83 × 10−3 mm2/s (arrow head). e Contrast-enhanced MRI showed both lesion heterogeneous enhancement
