    • E.

      EEG

    Correct Answer
    D. PET
    Explanation
    PET (Positron Emission Tomography) scan is a medical imaging technique that measures brain activity by injecting a radioactive glucose into the body. This radioactive substance allows the observation of how the brain is functioning, as it is taken up by the brain cells. The emitted positrons from the radioactive substance are detected by a scanner, which creates images of the brain activity. MRI (Magnetic Resonance Imaging) and CAT (Computerized Axial Tomography) scans are different imaging techniques that do not involve the use of radioactive substances. FMRI (Functional Magnetic Resonance Imaging) measures brain activity by detecting changes in blood flow, while EEG (Electroencephalography) measures electrical activity in the brain.
