Breast MRI (IMAGE)
Caption
Axial images show the incremental steps 1–4. (A) Step 1: The first step consisted of the dual high-temporal low-spatial and low-temporal high-spatial dynamic T1 series, from before contrast material injection to 120 seconds after contrast injection only. (B) Step 2: The second step added diffusion-weighted images to the series available from step 1. (C) Step 3: The third step added T2-weighted images to the series available from steps 1 and 2. (D) Step 4: The fourth and final step added non–fat-saturated T1-weighted precontrast images, all remaining dynamic phases acquired after the first 120 seconds after contrast administration, and enhancement curve kinetics to the series available from steps 1, 2, and 3. This final step is the full multiparametric breast MRI protocol that was used in the Dense Tissue and Early Breast Neoplasm Screening (DENSE) trial. The curve kinetics overlay is a colormap showing the standard three types of delayed curve kinetics: type-I kinetics, persistent increase (blue); type-II kinetics, plateau (yellow); and type-III kinetics, washout (red).
