| Research Abstract |
We evaluated a metabolic variation of tumors using positron emission tomography. Various metabolic patterns were demonstrated in our studies, and these results should be useful for diagnosis and therapy of various malignant tumors. An early response to radiation and/or chemotherapy was evaluated based on tumor shrinkage using CT images. The FMISO uptake in the tumor had a negative correlation with the tumor shrinkage after therapy. FMISO may be a good predictive indicator for therapy. Breast cancer showed various metabolic patterns, which may correlate with the intrinsic subtypes.
