Abstract:
Positron emission tomography (PET) is valuable for assessing the biochemistry and physiology of the human brain. A computerised brain atlas has been developed which allows demonstration of anatomical regions of PET images and manipulation of these images into a standardised anatomical space. Once the images are in this standardised three-dimensional space it is possible to make comparisons between individuals and groups of individuals. We describe the use of this atlas in the generation of a set of mean reference images using methionine PET images of normal volunteers.
