Figures & Tables

Figure 1

A: Nonenhanced axial T1-weighted magnetic resonance images with fat saturation and B: contrast-enhanced subtraction from a 49-year-old premenopausal woman demonstrate extremely dense fibroglandular tissue and marked background parenchymal enhancement. C: Time (x-axis) after intravenous contrast administration versus percentage enhancement (y-axis) reveals a gradually increased enhancement (type 1 pattern), Eearly = 28%, Epeak = 102%.

A: Nonenhanced axial T1-weighted magnetic resonance images with fat saturation and B: contrast-enhanced subtraction from a 53-year-old postmenopausal woman demonstrate almost entirely fatty breast and minimal background parenchymal enhancement. C: Time (x-axis) after intravenous contrast administration versus percentage enhancement (y-axis) reveals gradually increased enhancement (type 1 pattern), Eearly = 7%, Epeak = 22%.

A:Nonenhanced axial T1-weighted magnetic resonance images with fat saturation and B: contrast-enhanced subtraction from a 34-year-old premenopausal woman demonstrates heterogeneously dense fibroglandular tissue and minimal background parenchymal enhancement. Images C and D are from a 62-year-old postmenopausal woman, demonstrating scattered fibroglandular tissue and moderate parenchymal enhancement.
