Positron emission tomography (PET) is a new nuclear medicine technique. The number of PET facilities is limited due to the high costs and complexity of this diagnostic modality. The principles of PET are explained. The technique can be used to visualize and analyse tumor metabolism. Present applications include tumor detection, staging, determination of growth rate, malignancy grade and hormone receptor status.
正电子发射断层扫描（PET）是一种新型核医学技术。由于这种诊断方式成本高昂且操作复杂，PET设备的数量有限。本文解释了PET的原理。该技术可用于可视化和分析肿瘤代谢。目前的应用包括肿瘤检测、分期、生长速率测定、恶性程度分级以及激素受体状态评估。
