~(1?)F-氟脱氧葡萄糖(FDG)-PET显像已用于各种肿瘤的检查.有资料报道,骨骼肌肿瘤FDG摄取量与其组织分化程度相关.方法:共25例,18～86岁,病灶最小直径2cm,均有组织学诊断、CT和MRI扫描.恶性瘤19例,1级3例,2级6例,3级10例;良性瘤6例为0级.110～410MBq FDG静注15min后,PET显像产生7层横断面像(厚1.4cm),画ROI计算肿瘤/健侧相应部位组织的放射性比值(TBR).肿瘤病灶内的
~(1?)F-fluorodeoxyglucose (FDG)-PET imaging has been used for the examination of various tumors. There are data reported that FDG uptake of skeletal muscle tumors is related to the degree of histological differentiation. Methods: A total of 25 cases, 18 ~ 86-year-old, the smallest diameter of the lesion 2cm, there are histological diagnosis, CT and MRI scan. 19 cases of malignant tumors, 1 case of 3 cases, 2 cases of 6 cases, 3 cases of 10 cases; benign tumors in 6 cases of 0. 110 ~ 410MBq FDG 15min after intravenous injection, PET imaging produces 7-layer cross-sectional images (thickness 1.4cm), draw ROI to calculate the ratio of radiotherapy (TBR) in the corresponding tissue of the tumor/health side. Within the tumor lesions
