| الوصف: | Abstract Several limitations of [18F]FDG have been reported, such as nonspecific uptake of inflammation foci. Moreover, [11C]MET has been found to accumulate in normal and inflammatory tissues as well as tumors. To increase specificity to tumor tissues, PET probes with tumor-specific molecular targets have been actively developed. [18F]FIMP was found to be highly accumulated in LAT1-positive tumors but not in inflamed tissue. The aim of this study was to explore whether [18F]FIMP can be used for the early-phase evaluation of radiotherapy accompanied by inflammation, and compare its effectiveness with those of [11C]MET and [18F]FDG. Tumor uptake of [18F]FIMP decreased at day 1 after irradiation, and remained low until day 14. Comparatively, that of [18F]FDG initially decreased at day 3 but was transiently elevated at day 7 and then decreased again at day 10. Decreased tumor uptake of [11C]MET was observed at day 10. In line with the uptake of [18F]FIMP, the ratio of Ki-67 immuno-positive cells in tumor tissues significantly decreased at day 1, 7, and 10 as compared with that in the control. These findings suggest that [18F]FIMP may be a PET probe involved in the early detection and prediction of radiotherapy efficacy, although further clarification is needed. |
