| 内容記述 | The role of PET in clinical diagnosis of cancer and the evaluation of therapeutic effects were studied. PET studies using C-11 methionine were carried out in recent years in NIRS. The usefulness of whole-body PET using C-11 methionine was studied. Metastatic lesions were detected successfully by C-11 methionine whole-body PET. C-11 methionine PET was able to reveal tumors successfully in almost patients bearing cancer. It seemed C-11 methionine PET has the high specificity in detecting cancer. Applications of PET in the management of cancer therapy is under discussion, including assessment of response to HIMAC therapy. Combined PET-CT scanner that simultaneously reveals both PET and CT images within the body can indicate accurate fusion image of PET and CT image. We intended to measure the auto activation activity using PET-CT for the purpose of evaluating the accuracy of a superimpose method which we developed to display fusion image of the auto activation image of dedicated PET and CT planning image for HIMAC therapy. 71.4% of our cases showed good correspondence between PET-CT and dedicated PET fusion images. The orbital tumour showed some difference of each other, because FOV of planning CT for the orbital tumor was so narrow that the fitting algotithm tended to cause some errors. The maxillary sinus cancer showed also some difference between PET-CT and dedicated PET fusion images. Head position of the case at PET-CT measurement differed from that of planning CT, and the fusion images of the two studies differed each other. For clinical purpose, it seems to be better to evaluate the auto activity distribution that fused on planning CT. But, PET-CT measurement is very simple and easy to get fusion images. |
