SPECT instrumentation is more complex than that used for whole-body and planar imaging, and requires careful quality control to ensure optimum performance. Conventional and new hybrid SPECT imaging systems (coincidence and SPECT/CT) will be discussed. New imaging detector materials such as LSO and CZT will also be discussed, along with their potential advantages. Finally, basic SPECT quality control will be reviewed. After reading this article, the nuclear medicine technologist should be able to: (a) explain the use of single and multihead gamma cameras for SPECT imaging; (b) have an understanding of the potential of new hybrid SPECT imaging systems; (c) be aware of future developments in SPECT imaging technology; (d) understand the requirements for SPECT quality control, including field uniformity and center of rotation corrections; and (e) explain the benefits of using phantoms to augment SPECT quality control.
单光子发射计算机断层扫描（SPECT）仪器比用于全身和平面成像的仪器更为复杂，需要进行仔细的质量控制以确保最佳性能。本文将讨论传统和新型混合SPECT成像系统（符合成像和SPECT/CT）。还将讨论诸如硅酸镥（LSO）和碲锌镉（CZT）等新型成像探测器材料及其潜在优势。最后，将回顾基本的SPECT质量控制。阅读本文后，核医学技术人员应能够：（a）解释单头和多头伽马相机在SPECT成像中的应用；（b）了解新型混合SPECT成像系统的潜力；（c）知晓SPECT成像技术的未来发展；（d）理解SPECT质量控制的要求，包括视野均匀性和旋转中心校正；以及（e）解释使用体模增强SPECT质量控制的益处。
