Positron Emission Tomography (PET)

PET represents a new step forward in the way scientists and doctors look at the brain and how it functions. An X-ray or a CT scan shows only structural details within the brain. The PET scanner gives us a picture of the brain at work. - What is PET?

The epigraph above is reflective of the enthusiasm being generated among clinicians concerning the advent of positron emission tomography and its potential for imaging the human brain. The introduction of sophisticated neuroimaging techniques such as computerized tomography and magnetic resonance imaging has shifted the emphasis of neuropsychology from lesion localization to diagnosing the etiology of diseases (Maruish & Moses, 1997).

Behavioral neurology also benefited from innovations in neuroimaging techniques. The advent of improvements in the imaging of brain anatomy through computed tomography (CT) and magnetic resonance imaging (MRI), as well as functional imaging with single photon emission...
