NIMH Workshop on PET-MRI

PET and fMRI provide two separate and partially overlapping methods for neuroimaging. While PET relies on metabolic processing as measured by the dissipation of radioactive isotopes, MRI measures changes in blood oxygenation level (BOLD). Each method is useful for providing a quantitative metrics for brain function and dysfunction useful in the diagnosis and understanding of clinical brain disorders and normal development. The combination of methods adds values where the whole is greater than the sum of the parts. Much work in advancing research with combined PET-MRI has been done, and the invited experts discuss these advances and avenues of research.
