B- Scattered fibroglandular densities: Your breasts have more fatty tissues and a considerable quantity of fibroglandular tissues. Radiologists use mammogram images to grade breast tissue based on the proportion of dense to nondense tissue. B: Scattered areas of fibroglandular density indicates there are some scattered areas of density, but the majority of the breast tissue is nondense. Studies have shown substantial disagreement between radiologists when visually determining a patient's breast composition. Category D: Extremely dense, which lowers mammography sensitivity. D.
