PET-MRI Instrumentation | Original Article
Positron emission tomography-magnetic resonance imaging (PET-MRI) is the recent approach to functional and anatomical imaging. The state-of-the-art PET-MRI scanners simultaneously acquire functional PET and anatomical or functional MRI data. As function and anatomy are not totally independent of one another the images to be reconstructed are likely to have shared structures. PET provides metabolic information and the MRI anatomic structure. Thus, the two modalities provide complimentary information, and it has greatly enhanced its clinical applications like imaging in oncology, neurology, and cardiology. This paper gives an overall understanding of PEP- MRI system.
