| Outline of Final Research Achievements |
4DST has been developed as an in vivo cell proliferation marker based on the DNA incorporation method. The purpose of this study was to investigate the feasibility of 4DST PET/CT for the detection of gastrointestinal cancer, in comparison with FDG PET/CT, and determined the degree of correlation between two radiotracers and proliferative activity as indicated by the Ki-67 index. Gastrointestinal cancer were detected by both 4DST and FDG PET/CT studies. A significant correlation was observed between 4DST SUV and FDG SUV. A significant correlation was observed between 4DST SUV and Ki-67 index and for FDG SUV. These preliminary results indicate that 4DST PET/CT seems to be useful in detecting gastrointestinal cancer and in the noninvasive assessment of proliferation, as similar as FDG PET/CT.
