PET scans

• Brain positron emission tomography (PET) scans is an imaging test of the brain
• they use a radioactive substance called tracer to look for disease or injury in the brain
• It shows how the brain tissue is working
• They are helpful for diagnosing certain conditions such as depression, bipolar, OCD and other neurological disorders
• Patients undergoing a PET scan have the tracer injected into their blood
• When a quantity of blood collects in a particular area due to increased blood flow, the PET scan can detect where the blood is going
• If they had trouble recalling such memories and their doctor performed a PET scan, they may find a dysfunctional amount of activity in that brain area
• The PET scan is beneficial to cognitive neuroscience as it allows instant, real-time imaging of the brain and its functions, which can be used to gain a deeper understanding of a patient's condition and the brain
