WebFeb 14, 2024 · The electroencephalogram (EEG) is a neuroimaging test that can detect and record minute changes in electrical activity within the brain. This is recorded using microelectrodes (large, flat electrodes stuck to the skin or scalp). The electrical impulses in an EEG recording appear as wavy lines with peaks and valleys. WebPositron emission tomography (PET), which is similar to the MRI, is a scanning method that enables psychologists and doctors to study the brain (or any other living tissue) without surgery. PET scans use radioactive glucose (instead of a strong magnetic field) to help study activity and locate structures in the body.

WebPET Scan. A PET scan refers to the use of a Positive Emission Tomography machine. This type of machine uses a functional imaging technique that is meant to observe metabolic processes in three dimensions through the measurement of gamma rays that are indirectly emitted by a positron-emitting radionuclide that had been previously introduced into ... WebPositron emission tomography (PET) scans create pictures of the living, active brain (Figure 2). An individual receiving a PET scan drinks or is injected with a mildly radioactive substance, called a tracer. Once in the bloodstream, the amount of tracer in any given region of the brain can be monitored. cotton pajama short setWebFeb 9, 2024 · PET scans work by measuring the levels of sugar glucose in the brain to determine where neurons are firing from. This can work as neurons use glucose as their fuel. During a PET scan, a radioactive tracer substance is injected into the blood. breath tests for sibo
