European Journal of Nuclear Medicine and Molecular Imaging is a forum for the exchange of clinical and scientific information for the nuclear medicine community and allied professions involved in the functional, metabolic and molecular investigation of disease. The journal is primarily of interest to those practicing in the field of nuclear medicine but it also reports on original works relating to physics, dosimetry, radiation biology, computer science, radiochemistry and pharmacy. The journal welcomes original material reflecting the growing field of molecular imaging probes, reporter gene assays, cell trafficking, targeting of endogenous gene expression and antisense methodologies. EJNM publishes in-depth Reviews of topical interest, Occasional Surveys, Short Communications and correspondence. A section on Controversies is also new. Case reports are not published.
