Biodistribution results exhibited that radio ligand had good affinity in the infected site in rabbit.
Both positron emission tomography (PET) studies using specific radio ligands and postmortem pathologic studies showed that amyloid deposition, the earliest pathological accumulation in the course of the disease, starts from the brain areas which are part of default mode network.
One of the most popular topics in AD is molecular-based PET imaging targeting amyloid and tau depositions using specific radio ligands. The most important characteristic of this method is allowing the in vivo observation of pathologic changes in the brain as pathologists do in post-mortem brains.
