Abstract:

BACKGROUND: Positron emission tomography can reflect the cell metabolism and functional changes of cells at the molecular level. Magnetic resonance imaging can obtain images with higher soft-tissue contrast and better spatial resolution without ionizing radiation. With the fast development of multimodality molecular imaging techniques, positron emission tomography/magnetic resonance imaging as a multimodality molecular imaging technique can provide the molecular, morphological and functional information, so its clinical application is an anticipating focus of medical molecular imaging.
OBJECTIVE: To overview the progress and problems meet in the development of positron emission tomography/magnetic resonance imaging and to get a clear prospect of its potential clinical and scientific application.
METHODS: The CNKI database, SpringerLink database and PubMed database were searched by the first author for the related articles from January 2000 to June 2012. The English key words were “PET/MRI” and “multimodality molecular imaging or image fusion”, and the Chinese key words were “molecular imaging” and “image fusion”. The articles related to positron emission tomography/magnetic resonance imaging multimodality molecular imaging technique were selected, and for the articles in the same field, those published recently or in the authorized journals were selected. A total of 53 articles were included.
RESULTS AND CONCLUSION: From the existing research results, positron emission tomography/magnetic resonance imaging have more advantages over traditional and other multimodality imaging techniques such as positron emission tomography/computed tomography and single-photon emission computed tomography/ computed tomography, as demonstrated by the pre-clinical studies and preliminary clinical experiences, and have broader development space. So it has capacity to bring the development of molecular imaging technique and clinical diagnosis into a new area.
