Simultaneous
MR-PET data acquisition immediately brings to mind the possibility of
improving the performance of one instrument by using the information obtained
from the other modality. A number of aspects have to be considered in PET for
obtaining a correct quantitative measure of the activity concentration in a
specific voxel. Examples include the
attenuation and motion correction and the arterial input function
estimation. The accuracy of these
methods, in principle, could be improved by including the MR information.
