Question

Quizplus · Accepted Answer

SPECT (Single Photon Emission Computed Tomography) is a newer brain-imaging technique that uses a radioactive tracer to produce three-dimensional images of the brain. It is commonly used to assess blood flow, metabolism, and brain activity. EEG (Electroencephalography) measures electrical activity in the brain through electrodes placed on the scalp. TMS (Transcranial Magnetic Stimulation) uses magnetic fields to stimulate different regions of the brain, while EMG (Electromyography) measures muscle activity. While these are all useful techniques, SPECT is the newest addition to the list of brain imaging methods mentioned in the question.
