Positron Emission Tomography [PDF]

, 2006
Positron emission tomography (PET) is based on the detection in coincidence of the two 511-keV annihilation radiations that originate from β + -emitting sources, such as the patient containing β + -emitting radioactivity. Positrons are annihilated in body tissue and produce two 511-keV annihilation photons that are emitted in opposite directions (180°).

We report the correlation of the neuro-ophthalmological findings with a 18 F-fluorodeoxyglucose positron emission tomography-computed tomography study ( 18 F-FDG-PET/ CT) in a pediatric patient affected by a pure right homon- ymous hemianopia manifested after minor head injury and no evidence of any lesions at other neuroimage studies, visual evoked ...

Positron emission tomography

Clinical Physics and Physiological Measurement, 1988
While positron emission tomography (PET) represents the most advanced methodology using radiotracers, it is subject to two main constraints. The first is the physical accuracy with which the regional distribution, time course and concentration of the tracer can be determined. This is principally a function of the instrumentation.
