Positron emission tomography (PET)/computerised tomography is now established in clinical practice for oncologic and non-oncological applications. Improvement and development of scanner hardware has allowed faster acquisitions and wider application. PET/magnetic resonance imaging offers potential improvements in diagnostic accuracy and patient acceptability but clinical applications are still being developed. A range of new radiotracers and non-radioactive contrast agents is likely to lead to a growth in hybrid molecular imaging applications that will allow better characterisation of disease processes.
正电子发射断层扫描（PET）/计算机断层扫描现在已在肿瘤学和非肿瘤学应用中确立了临床实践地位。扫描仪硬件的改进和发展使得采集速度更快，应用范围更广。PET/磁共振成像（MRI）在提高诊断准确性和患者接受度方面具有潜在优势，但临床应用仍在开发中。一系列新型放射性示踪剂和非放射性对比剂可能会导致混合分子成像应用的增长，从而更好地描述疾病过程。
