Combined 18F-FDG-FDOPA tumor imaging for assessing response to therapy.

The article on imaging metastatic melanoma with 18F-FDG, 6-fluoro-l-dopa (FDOPA), and 15O-water, by Dimitrakopoulou-Strauss et al. ([1][1]) in this issue of The Journal of Nuclear Medicine , raises several interesting issues likely to be important in the evolution of PET in oncology. These issues
