Molecular Imaging of Infections: Advancing the Search for the Hidden Enemy

Abstract

Abstract Even before the coronavirus disease 2019 pandemic, infections were a major threat to human health, as the third leading cause of death and the leading cause of morbidity among all human diseases. Although conventional imaging studies are routinely used for patients with infections, they provide structural or anatomic information only. Molecular imaging technologies enable noninvasive visualization of molecular processes at the cellular level within intact living subjects, including patients, and hold great potential for infections. We hope that this supplement will spur interest in the field and establish new collaborations to develop and translate novel molecular imaging approaches to the clinic.
