Figure 1. Diagram shows a breast imaging interpretation model that incorporates data obtained in 192 patients. Each node of the tree-shaped model includes the defining architectural feature, the number of patients with cancer and benign disease, and the associated NPV and PPV.

Figure 6a. T2-weighted fast spin-echo MR image (4,000/110) (a) and contrast-enhanced fast multiplanar spoiled gradient-echo MR image (50/8, 45° flip angle) (b) show a focal mass (arrow) in a 75-year-old woman with a palpable mass that was visible at mammography and that proved to be colloid carcinoma.

Figure 7. Figures 7, 8. (7) Contrast-enhanced fast multiplanar spoiled gradient-echo MR image (25/4, 30° flip angle) shows a smooth mass (arrow) in a 46-year-old woman who had calcifications and a mass that were visible at mammography and that proved to represent a fibroadenoma. The thick swirls of low signal intensity seen within the mass are a variant of the nonenhancing internal septations seen in association with fibroadenoma. (Adapted and reprinted, with permission, from reference 1.) (8) Contrast-enhanced fast multiplanar spoiled gradient-echo MR image (300/3, 90° flip angle) shows a very large smooth mass (arrows) in a 30-year-old woman with a palpable and mammographically visible mass that proved to be a giant fibroadenoma.

Figure 9. Figures 9, 10. (9) Contrast-enhanced fast multiplanar spoiled gradient-echo MR image (50/8, 45° flip angle) shows a lobulated mass (white arrow) with nonenhancing internal septations in a 21-year-old woman with a palpable mass that proved to be a fibroadenoma. Black arrow indicates an internal septation. (Adapted and reprinted, with permission, from reference 1.) (10) Contrast-enhanced fast multiplanar spoiled gradient-echo MR image (50/6, 60° flip angle) shows a lobulated mass (white arrow) with nonenhancing internal septations in a 49-year-old woman with mammographically visible calcifications who proved to have a fibroadenoma. Black arrow indicates an internal septation.

Figure 13a. T2-weighted fast spin-echo MR image (4,000/120) (a) and contrast-enhanced fast multiplanar spoiled gradient-echo MR image (50/6, 60° flip angle) (b) show an irregular mass (arrows) with nonenhancing internal septations in a 36-year-old woman with a palpable mass who proved to have fibrocystic change. The mass contains discrete cysts that have high T2 signal and do not enhance centrally with contrast material.
