Question

Quizplus · Accepted Answer

PET (Positron Emission Tomography) imaging uses annihilation events to detect gamma rays emitted by a radioactive tracer injected into the bloodstream. This technique allows researchers to track metabolic and biochemical processes in the brain, as the tracer accumulates in areas with higher levels of activity. MEG (Magnetoencephalography), fMRI (Functional Magnetic Resonance Imaging), and EEG (Electroencephalography) are also brain imaging techniques but do not use annihilation events.
