WebBut instead of creating images of organs and tissues like MRI, fMRI looks at blood flow in the brain to detect areas of activity. These changes in blood flow, which are captured on a computer, help doctors understand more about how the brain works. The concept behind MRI has been around since the beginning of the 20th century. WebPET scan measure radioactivity from the F atoms that is coupled to glucose molecules. Since ur brain use glucose as its main energy source the more radioactivity you see the more active that brain area is. U can use fMRI and PET to measure both brain activity and see its structure. CAT and MRI only show u brain structure. cfern074 • 3 yr. ago
