Outline of Final Research Achievements

A hybrid scanner of positron emission tomography (PET) and magnetic resonance imaging (MRI), PET/MRI, has been developed as a next-generation diagnostic technology. In order to generate an accurate PET image, MRI imaging for creating correction data has been additionally performed so far. In this study, we succeeded in creating correction data using only MRI images used for standard diagnosis.This makes it possible to diagnose more patients within a unit time.
