Single-Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) use radioactive tracers which are taken up where blood flow is greater. SPECT and PET therefore provide images of blood flow (again, considered by most scientists as a sign of greater brain activity) in different parts of the brain. However, they do not provide as much anatomical detail as MRI or CT scans.
