| 内容記述 | We objectively compared C-11 methionine (MET) PET/CT and contrast-enhanced (CE) CT images to clarify the difference in diagnostic information using fusion software with a registration algorithm. Eleven patients with adenoid cystic carcinoma (ACC) and twelve patients with malignant melanoma (MM) in head and neck region were studied PET/CT as well as CECT obtained separately. All patients received PET/CT and CECT before carbon ion radiotherapy (CIRT) and fifteen patients received both studies after CIRT. CT image from PET/CT and CECT image were registered automatically by PMOD software based on Mutual Information. And then CT image from PET/CT was replaced with PET image from PET/CT and we got PET/CECT fusion image, and were evaluated according to the four-grade system such as "Matched" with each other, "Embraced " the other, partially "Overlapped" and "Separated" with each other. Matched-grade,Embraced-grade,verlapped -grade and Separated-grade were 42.1%,39.5%,7.9% and 10.5% in all studies, respectively. Combination of Matched and Embraced-grade was 72.7% studies in ACC and 93.8% studies in MM. Before CIRT, it was 100% in ACC and 91.7% in MM. After CIRT, it was 45.5% in ACC and 100% in MM. MET accumulation and CT enhancement area tended to match before CIRT, but tended to mismatch after CIRT in ACC. It also tended to match mostly both before and after CIRT in MM. |
