Novel PETSPECT Probes for Imaging of Tau in Alzheimer’s Disease

الملخص EN

As the world’s population ages, the number of patients with Alzheimer’s disease (AD) is predicted to increase rapidly.

The presence of neurofibrillary tangles (NFTs), composed of hyperphosphorylated tau protein, is one of the neuropathological hallmarks of AD brain.

Since the presence of NFTs is well correlated with neurodegeneration and cognitive decline in AD, imaging of tau using positron emission tomography (PET) and single-photon emission computed tomography (SPECT) is useful for presymptomatic diagnosis and monitoring of the progression of AD.

Therefore, novel PET/SPECT probes for the imaging of tau have been developed.

More recently, several probes were tested clinically and evaluated for their utility.

This paper reviews the current state of research on the development and evaluation of PET/SPECT probes for the imaging of tau in AD brain.
