PET (positron emission tomography) PET stands for Positron Emission Tomography. imaging) uses a combination of powerful magnets and radio pulses to London: Macmillan. Electroencephalography (EEG) serves this purpose by providing a measure of a brain’s electrical activity. The Brain (6), 495 - 508, , GROSS, R.

Actually, melanoma was one … PET/CT is a diagnostic imaging tool that combines two scan techniques: positron emission tomography (PET) and computed tomography (CT). [CDATA[ about the implications of their findings. Fallon used positron emission tomography (PET) scans, which are scans that produce colored maps of brain activity by detecting the metabolism level of injected substances such as glucose made mildly radioactive to show which parts of the brain are most active, in order to observe the brains of already classified psychopaths compared to the PET . experiment using an independent measures design. Patients who suffer from epilepsy show an increase of the amplitude of firing visible on the EEG record.
