目的：评价国产ＰＥＴＢ０１和国产１８ＦＦＤＧ的临床应用价值。方法：应用国产ＰＥＴＢ０１和国产１８ＦＦＤＧ对１８例患者进行ＰＥＴ显像。所有患者均先行透射扫描后再行相同部位发射扫描，部分心肌扫描于注射前１ｈ口服葡萄糖５０ｇ，其余患者均禁食＞６ｈ后进行ＰＥＴ检查。结果：４例发作间期癫痫患儿中，３例可见局部皮质代谢减低区；２例脑血管患者均见和体征相关部位皮质代谢减低。４例糖负荷心肌显像中，心动超声确定运动功能减低心肌片段中３８％表现严重ＦＤＧ摄取减低，其余表现正常摄取或轻度减少。６例肿瘤患者中，３例可见肿瘤ＦＤＧ摄取增高，２例治疗后肿瘤ＦＤＧ摄取减低，１例肝癌未见明显ＦＤＧ摄取。结论：１８ＦＦＤＧＰＥＴ显像技术可反映体内正常脏器和病变糖代谢状态，可用于临床疾病诊断和判断治疗效果，有重要临床应用价值。但１８ＦＦＤＧＰＥＴ显像易受血糖、炎症等因素影响，缺乏特异性
Objective: To evaluate the clinical application of domestic PET B01 and domestic 18F FDG. Methods: 18 patients with domestic PET B01 and domestic 18F FDG PET imaging. All patients were scanned with the same site after the first transmission scan, some myocardial scan 1h before injection of oral glucose 50g, the remaining patients were fasting> 6h after PET examination. Results: In 4 children with interictal epilepsy, the cortical metabolism was reduced in 3 cases and in 2 cases of cerebrovascular disease. In 4 cases of myocardial infarction with myocardial infarction, echocardiographic determination of motor function reduced 38% of the myocardial sections in the myocardial infarction group, which showed a significant decrease in FDG uptake, while the rest showed normal uptake or mild decrease. Among the 6 cancer patients, FDG uptake was increased in 3 cases, FDG uptake in 2 cases decreased, and FDG uptake was not found in 1 case. Conclusion: 18F FDG PET imaging technology can reflect the status of normal organs and diseased glucose metabolism in vivo, which can be used to diagnose and judge the clinical disease and have important clinical value. However, 18F FDG PET imaging susceptible to blood glucose, inflammation and other factors, the lack of specificity
