Abstract
Using a radioisotope, positron emission tomography (PET) can obtain images of natural circulation through the body (from blood vessels to organs and from organs to blood vessels) as molecular images, which is naturally present in vivo. A distinctive feature of PET molecular imaging is to use radioisotope compounds as tracers. This chapter describes the latest status of imaging research on neurological functions, to the extent to which they are related to PET. Although PET has limitations, e.g., on spatial resolution, radiation exposure and observation period due to short half-life isotopes, it can visually and dynamically evaluate normal brain function and pathophysiology. Newly-developed imaging devices (e.g., semiconductor PET and PET/MR), in combination with improved imaging techniques and innovative analytical procedures, are expected to be powerful tools for studying the brain function in detail.
