| Research Abstract |
19F MRS/MRI using 2-deoxy-2-fluoro-D-glucose(FDG) was explored as a method for quantitative imaging towards characteristic diagnosis of tumor. 19FDG metabolic images were obtained at the tumor position at 0. 5, 3, 24, 48 hour after FDG injection. Metabolites were quantified in tumor tissue and organs excised after the imaging, and the detailed analysis was performed as water extracts by 19F NMR. In the excised tissue, FDG metabolites were retained for a long time at the high concentration. 19F MRS/MRI was shown to be an excellent method for tumor characterization reflecting metabolic specificity.
