正电子发射断层扫描(PET)是一种分子成像方法,从功能,生物化学的角度对人体进行非侵入性成像。PET非常敏感,可以检测到微量(飞摩尔)的放射性示踪剂。然而,由于光子散射,图像不具有与CT或MRI一样高的空间分辨率,也不提供太多解剖信息。出于这个原因,PET通常与CT结合在混合扫描仪中,这使得能够更精确地对放射性进行解剖定位。PET/CT联合成像比单独使用任何一种技术提供更好的诊断信息(图1)。
Positron emission tomography (PET) is a molecular imaging method that images the human body non-invasively from a functional, biochemical perspective. PET is extraordinarily sensitive and can detect minute (femtomolar) quantities of radioactive tracers. However, because of photon scattering, the images do not have as high spatial resolution as CT or MRI nor do they provide much anatomical information. For this reason, PET is routinely combined with CT in hybrid scanners, which enables more precise anatomical localization of radioactivity. Combined PET/CT imaging provides better diagnostic information than either technique alone (Figure 1).
