Positron emission tomography (PET) is a procedure in nuclear medicine, which is applied predominantly in oncological diagnostics. In the form of modern hybrid machines, such as PET computed tomography (PET/CT) and PET magnetic resonance imaging (PET/MRI) it has found wide acceptance and availability. The PET procedure is more than just another imaging technique, but a functional method with the capability for quantification in addition to the distribution pattern of the radiopharmaceutical, the results of which are used for therapeutic decisions. A profound knowledge of the principles of PET including the correct indications, patient preparation, and possible artifacts is mandatory for the correct interpretation of PET results.
正电子发射断层扫描（PET）是核医学中的一种检查方法，主要应用于肿瘤诊断。以现代混合型设备的形式，如PET计算机断层扫描（PET/CT）和PET磁共振成像（PET/MRI），它已得到广泛认可并得以普及。PET检查不仅仅是另一种成像技术，而是一种功能方法，除了放射性药物的分布模式外还具备定量能力，其结果用于治疗决策。要正确解读PET结果，必须深入了解PET的原理，包括正确的适应症、患者准备以及可能出现的伪影。
