PET-MRI: the likely future of molecular imaging

PET-CT is a successful combination of functional and morphologic information.and it has already been shown to have great value both in clinics and in scientific research.MRI is another kind of morphologic imaging method,in contrast to CT,MRI can yield images with higher sof t-tissue contrast and better spatial resolution.The combination of PET and MRI for simultaneous data acquisition should have far. reaching consequences for molecular imaging.This review will talk about the problems met in the development of PET-MRI and describe the progress to date and look forward to its potential application.
