1 The next biological factor which will be discussed with the brain imaging technology of PET Scans are brain interactions and functions. 2  Describe PET brain imaging technology. 3  PET scans require patients to be injected with a radioactive glucose tracer which shows the areas where glucose is absorbed in the active brain. In the following essay, the brain imaging technologies that will be discussed are MRI and PET scans, which will be investigated in terms of its role in investigating the correlations/relationships between biological factors and behaviour.
