Abstract
PET imaging can provide information about the biochemical brain function, for instance, rate of glucose metabolism and density of a specific receptor, using a variety of radiopharmaceuticals. The resolutions of the PET images are not very high, and the images do not include much morphologic information. Thus, MR images of same subjects are often used in the PET image analysis. The use cases, such as the registration and superimpose of the images, the application in the statistical comparison, and the improvements of the accuracy of the PET analysis using MR Images, are shown in this article.
