摘要
淀粉样蛋白正电子发射断层扫描(positron emission tomography,PET)成像能有效显示活体内神经炎性斑块含量。淀粉样蛋白PET成像对鉴别阿尔茨海默病(Alzheimess disease,AD)与健康对照者的特异性较结构性核磁共振成像高,鉴别AD和健康对照者的灵敏度高于氟代脱氧葡萄糖PET成像,且有更高可靠性。AD患者淀粉样蛋白PET成像与脑脊液A-beta 42的结果高度一致。本文就淀粉样蛋白PET成像技术在AD临床诊断中应用的研究进展作一综述。
Amyloid positron emission tomography(PET)is a valid in vivo marker of neuritic plaque load.The specificity of amyloid PET for discriminating Alzheimers disease(AD)from healthy controls is higher than that of structural MRI,and the sensitivity is also higher than that of fluorodeoxyglucose-PET,with a high interreader reliability.There is a high concordance between the results of amyloid PET and cerebrospinal fluid A-beta 42 for AD patients.This paper reviews the current research progression of amyloid PET in the diagnosis of AD.
