Noninvasive molecularly targeted imaging may play a critical role in aiding visualization and understanding of the systemic damage. We have identified αvβ6 as a molecular target; an epithelium-specific cell surface receptor that is low or undetectable in healthy adult epithelium but upregulated in select injured tissues, including fibrotic lung. Herein we report the first human PET/CT images using the integrin αvβ6-binding peptide (18F-αvβ6-BP) in a patient 2 mo after the acute phase of infection. Minimal uptake of 18F-αvβ6-BP was noted in normal lung parenchyma, with uptake being elevated in areas corresponding to opacities on CT. This case suggests that 18F-αvβ6-BP PET/CT is a promising noninvasive approach to identify the presence and potentially monitor the persistence and progression of lung damage. ER -
