Figure 1c:

Axial high-spatial-resolution gradient-echo fat-suppressed MR sections (2.0 × 2.4-cm field of view) obtained through the mammary glands of three mice, with corresponding gadolinium concentration–time curves and TCM fits displayed in black show (a) a normal mammary gland (darker area outlined in white), (b) an intramammary lymph node (arrowhead), (c) DCIS (arrows), and (d) a tumor (arrowhead). The lymph node, DCIS, and tumor appear clearly against the darker background of the normal mammary gland. In each image, the gray curve represents the gadolinium concentration–time curve in an ROI drawn on the back muscle for the sake of comparison. All plots are scaled from −0.1 to 0.6 mmol/L.
