Diagnosis value of the research of ^(18)F-FDG PET/CT scan on patient with solitay pulmonary nodule

目的本文运用18F-FDG PET/CT对孤立性肺结节病进行扫描来探讨其诊断价值。方法患者禁食6小时以上,按0.12 mci/kg经静脉注入18F-FDG示踪剂于体内。注射前监测血糖,需要注射胰岛素控制血糖在≤7.8 mmol以下,再行静脉注入18F-FDG示踪剂。注射后平静休息60 min,然后,在自然平静呼吸下行全身GE Discovery LS PET/CT扫描仪检查。结果病理检查显示21例诊断肺癌,8例为良性肿瘤;PET/CT扫描检查显示23例诊断肺恶性肿瘤,6例患者为良性肿瘤。结论 18F-FDG-PET/CT显像对SPN有很好的诊断价值,能进一步提高诊断的准确率,值得临床广泛开展。

Objective To study the diagnosis value of 18F-FDG PET/CT were scanned patients with solitay pulmonary nodule.Methods To choose the patients examined according to fast more than six hours of,0.12 MCI/kg by intravenous injection 18F-FDG tracer in the body.Before the injection,Blood glucose was examined,when the patien,s sugar holds mmol blood sugar concentration than 7.8,need insulin injections in controlling blood sugar ≤7.8 mmol below,republished intravenous injection 18F-FDG tracer.The tracer injection after 60 min,then quietly rest in natural quiet breathing,descending systemic GE Discovery of PET/CT scanner check LS.Results Histopathological examination revealed 21 patients with diagnosis lung cancer,8 patients with benign tumor;PET/CT scan showed 23 cases diagnosed lung malignancy,6 patients with benign tumors.Conclusion 18F-FDGPET/CT imaging to SPN have very good diagnostic value,can further improve the diagnosis accuracy,worth clinical extensively.
