Positron emission tomography–magnetic resonance imaging
Positron emission tomography–magnetic resonance imaging (PET-MRI) is a hybrid imaging technology that incorporates magnetic resonance imaging (MRI) soft tissue morphological imaging and positron emission tomography (PET) functional imaging.
==Applications==
Presently, the main clinical fields of PET-MRI are oncology, cardiology and neurology.〔http://www.nih.gov/news/health/sep2011/cc-26.htm〕 Research studies are actively conducted at the moment to understand benefits of the new PET-MRI diagnostic method. The technology combines the exquisite structural and functional characterisation of tissue provided by MRI with the extreme sensitivity of PET imaging of metabolism and tracking of uniquely labeled cell types or cell receptors.
There is discussion and investigation into utilizing PET-MR with Ion Therapy for the purpose of cancer treatment.〔http://www.dkfz.de/en/medphys/heavy_ion_therapy/index.html〕 with〔http://www.dkfz.de/en/presse/pressemitteilungen/2013/dkfz-pm-13-23-A-Sharper-Image-with-Combined-PET-MR-Technology.php〕 MRI's ability to accurately depict the proton density of tissue is a good match for the benefits and technical challenges of treatment planning utilizing Ion Therapy systems.
