Rapid advances in imaging technology are a challenge for health care professionals, who must determine how best to use these technologies to optimize patient care and outcomes. Hybrid imaging instrumentation, combining 2 or more new or existing technologies, each with its own separate history of clinical evolution, such as PET and CT, may be especially challenging. CT and PET provide complementary anatomic information and molecular information, respectively, with PET giving specificity to anatomic findings and CT offering precise localization of metabolic activity. Historically, the acquisition and interpretation of the 2 image sets have been performed separately and very often at different times and locales. Recently, integrated PET/CT systems have become available; these systems provide PET and CT images that are acquired nearly simultaneously and are capable of producing superimposed, coregistered images, greatly facilitating interpretation. As the implementation of this integrated technology has become more widespread in the setting of oncologic imaging, questions and concerns regarding equipment specifications, image acquisition protocols, supervision, interpretation, professional qualifications, and safety have arisen. This article summarizes the discussions and observations surrounding these issues by a collaborative working group consisting of representatives from the American College of Radiology, the Society of Nuclear Medicine, and the Society of Computed Body Tomography and Magnetic Resonance.
成像技术的飞速发展对医疗保健专业人员构成了挑战，他们必须确定如何最好地利用这些技术来优化患者护理和治疗结果。混合成像仪器结合了两种或更多种新的或现有的技术，每种技术都有其独立的临床发展历史，如正电子发射断层扫描（PET）和计算机断层扫描（CT），可能尤其具有挑战性。CT和PET分别提供互补的解剖学信息和分子信息，PET赋予解剖学发现特异性，CT提供代谢活性的精确定位。从历史上看，这两组图像的采集和解读是分开进行的，而且常常是在不同的时间和地点。最近，集成式PET/CT系统已经问世；这些系统提供几乎同时采集的PET和CT图像，并且能够生成叠加的、配准的图像，极大地便利了解读。随着这种集成技术在肿瘤成像领域的应用越来越广泛，关于设备规格、图像采集协议、监管、解读、专业资质和安全性等问题和担忧也随之出现。本文总结了由美国放射学会、核医学学会以及计算机体层摄影与磁共振学会的代表组成的协作工作组围绕这些问题进行的讨论和观察结果。
