Research Abstract |
Positron emission tomograophy (PET) using positron labeled amino acids has excellent diagnostic ability for gliomas. Although ^<11>C-labeled Methionine has been conventionally used, it is not convenient because of the short half life of ^<11>C. Since the half life of ^<18>F has much longer than that of ^<11>C, diagnostic usefulness of a ^<18>F-labelled amino acid PET tracer should be more convenient in clinical use. Therefore, we evaluated the usefulness of ^<18>F-DOPA for the diagnosis of gliomas. We found that the degree of accumulation of the ^<18>F-DOPA tracer could well reflect both the expanse and the malignancy of gliomas. These results suggest that ^<18>F-DOPA PET is a convenient and powerful tool for the pathological evaluation of gliomas.
