Answer :

Final answer:

The correct imaging technique used to measure the metabolic activity of the brain is a PET scan. This method utilizes a radioactive tracer to visualize active brain regions, aiding in both research and diagnosis of neurological conditions. While effective, PET scans do have limitations including radiation exposure and lower temporal precision.


Explanation:

Understanding PET Scans as a Tool for Measuring Brain Activity

When measuring the metabolic activity of the brain, the best imaging technique is a PET scan (Positron Emission Tomography). This diagnostic imaging procedure uses a radioactive tracer to visualize different areas of the brain in action. As brain regions become more active, blood flow to those areas increases, allowing for a clear picture of where metabolic activity is happening.

The PET scan involves either drinking or being injected with a mildly radioactive substance, after which a computer can monitor the movement of the tracer within the bloodstream. This method not only helps in understanding healthy brain function but is also crucial for diagnosing conditions such as Alzheimer’s disease and other neurological disorders.

While PET scans provide insightful data on brain activity, they have limitations, including exposure to radiation and a lack of precise temporal resolution. They are often supplemented by other imaging techniques such as fMRI (functional Magnetic Resonance Imaging) for more detailed analysis.
