Sıçan Böbrek Nakli sonra Akut Allogreft Reddi non-invaziv Görüntüleme Kullanımı ¹⁸ F-FDG PET

Executive Industry Relevance

Non-invasive imaging of acute allograft rejection using ¹⁸F-FDG PET in rat renal transplantation models addresses a critical need for early, specific, and repeatable detection of rejection events. This capability enables more predictive and less invasive monitoring, reducing reliance on biopsy and supporting translational continuity from preclinical models to clinical research. The approach enhances portfolio decision-making by providing quantitative, reproducible data for mechanistic de-risking and target validation in transplant immunology.
