| 内容記述 | To evaluate whether MET PET is valuable for imaging of osteosarcoma before and after carbon-ion radiotherapy (CIRT). 18 patients with osteosarcoma were performed with MET-PET before and after CIRT and analyzed visually and quantitatively. 16(88.9%) patients with osteosarcoma were clearly visible in the baseline MET PET study with a mean T/N ratio of 5.2+-2.9. The MET uptake decreased siginificantly to 2.6+-1.1 after CIRT(p<0.001). A siginificant reduction of tumor MET uptake of 39%+-27% was observed after CIRT. 16(88.9%) patients showed no local recurrence after CIRT with a median follow-up time of 20 months. Residual viable cells and necrosis of osteosarcoma were easily identified on MET PET image after CIRT. The results of this study showed that osteosarcoma could be effectively imaged with MET PET. MET PET might provide important metabolic information and help to distinguish residual viable cells and necrosis in osteosarcoma after CIRT. Thus this data permit the possible use for the therapeutic monitoring osteosarcoma treated by CIRT. | |||||
