Investigation progress of PET reporter gene imaging

Molecular imaging for gene therapy and gene expression has been more and more attractive, while the use of gene therapy has been widely investigated and intense research have allowed it to the clinical setting in the last two-decade years. In vivo imaging with positron emission tomography (PET) by combination of appropriate PET reporter gene and PET reporter probe could provide qualitative and quantitative information for gene therapy. PET imaging could also obtain some valuable parameters not available by other techniques. This technology is useful to understand the process and development of gene therapy and how to apply it into clinical practice in the future.
