The combination of positron emission tomography (PET) scanners and x-ray computed tomography (CT) scanners into a single PET/CT scanner has resulted in significant improvements in the diagnosis and staging of disease, particularly in the field of oncology. A decade on from the publication of the details of the first PET/CT scanner, we review the technology and applications of the modality. We examine the design aspects of combining two different imaging types into a single scanner, and the artefacts produced such as attenuation correction, motion and CT truncation artefacts. The article also provides a discussion and literature review of the applications of PET/CT to date, covering detection of tumours, radiotherapy treatment planning, patient management, and applications external to the field of oncology.
将正电子发射断层扫描(PET)扫描仪与X射线计算机断层扫描(CT)扫描仪整合到一台PET/CT扫描仪中,已在疾病的诊断和分期方面带来了显著改善,尤其是在肿瘤学领域。自第一台PET/CT扫描仪的详细信息公布十年后,我们回顾了该技术及其应用。我们研究了将两种不同成像类型整合到一台扫描仪中的设计方面,以及所产生的伪影,如衰减校正、运动和CT截断伪影。本文还对PET/CT迄今为止的应用进行了讨论和文献综述,涵盖肿瘤检测、放射治疗计划、患者管理以及肿瘤学领域之外的应用。
