Since my experience with brain scans is limited, can someone tell me if I have the following correct: CT scan: uses xrays, the scan is good for revealing the structure of the ear perhaps, but very little detail of the brain MRI: uses magnets, reveals more detail of the brain's structure fMRI: also using magnets, but reveals the activity of the neurons in the brain by detecting changes in oxygen in the blood (oxygen used by active neurons) PET: requires the injection of a radioactive substance that contains glutamate, detects activity in the brain via neurons using up the glutamate
Question: fMRI and PET scans look very similar. How can students tell them apart? When is one of these scans preferred over the other? Michael Michael A.
