Based on an already published fluorescent peptide (GE‐137)32 that was successfully employed for the identification of colorectal polyps in humans after intravenous administration, Arulappu et al.45developed 18F‐AH113804 for c‐Met detection via PET. The peptide was shown to bind c‐Met with high specificity and with a binding affinity of about 2 nM (Kd). Here, MET is linked to polyp of large intestine.
