Figure 4c. Type II curve in a multifocal and bilateral invasive lobular carcinoma in a 39-year-old woman. (a) Contrast-enhanced T1-weighted fat-saturated GRE (20/4.5; flip angle, 30°) image shows regional nonmass enhancement. (b) Color-coded map shows foci with the maximum slope of enhancement increase (red) after contrast material injection. Two foci were selected as regions of interest (ROIs). (c) Curves indicate plateau enhancement. The vertical axis indicates the percentage of enhancement, and the horizontal axis indicates the time in minutes.
