Mr. Alda has been showing early signs of memory loss and reduced cognitive ability. His doctors recommend a special type of neuroimaging that examines the flow of oxygenated blood and glucose metabolism in the brain. What is this imaging called?
  1. Electroencephalography (ECG)
  2. Rorschach Ink Blots
  3. Positron Emission Tomography (PET)
  4. Functional Magnetic Resonance Imaging (or fMRI)
  5. IAT
Explanation
Answer: C - Positron Emission Tomography (PET) neuroimaging examines the flow of oxygenated blood and glucose metabolism in the brain.
Key Takeaway: PET imaging is very useful in examining the brains of people suffering from early signs of memory loss and reduced cognitive ability. PETs provide images of the brain that indicated reduced blood flow and glucose metabolism which may point to a disease such as Alzheimer’s or an event such as a stroke or an aneurysm. PET imaging is used as one of the tests to uncover where the reduced cognitive ability may be stemming from in the brain.
