The figure shows the different expression of the biomarker (EDB-FN) and probe binding (ZD2) in slow-growing ER-positive breast cancer (not much yellow and red color representing low expression of the biomarker and low binding), and in triple- negative breast cancer (TNBC, high expression and high binding). As a result, the targeted contrast agent produced weak signal enhancement (brightness) in the former and strong signal (brightness) in the latter as pointed by the arrow. The technology is able to provide accurate detection and risk-stratification of aggressive BC.
