Innovations in molecular imaging have emerged with development of novel PET tracers enhancing cancer diagnosis. Shandong Cancer Hospital introduced a peptide-based tracer outperforming ^18F-FDG in detecting PD-L1 expression in head and neck cancers, improving precision oncology applications. Additionally, Johns Hopkins University presented ^18F-Fluorodeoxysorbitol (^18F-FDS), a radiotracer with high specificity for diverse invasive mold infections prevalent in immunocompromised patients, enabling early, noninvasive detection and improved management.
