Positron Emission Tomography (PET)

Positron emission tomography (PET) is an imaging test conducted in the Nuclear Medicine Department. It is used to measure the concentration of specific molecules in the brain.

There are different types of PET:

  • Amyloid PET measures the accumulation of abnormal amyloid protein in the brain, a key characteristic of Alzheimer’s disease.
  • Tau PET allows for the detection of abnormal tau protein in the brain, which is related to neuronal degeneration and cognitive function loss.
  • FDG PET is an imaging technique used to assess glucose metabolism in the brain, revealing aspects of its function. Alzheimer’s disease often shows reduced glucose metabolism in specific brain areas.
