Nuclear Cardiology for the past 40 years has distinguished itself in its ability to non-invasively assess regional myocardial blood flow and identify obstructive coronary disease. This has led to advances in managing the diagnosis, risk stratification, and prognostic assessment of cardiac patients. These advances have all been predicated on the collection of high quality nuclear image data. National and international professional societies have established guidelines for nuclear laboratories to maintain high quality nuclear cardiology services. In addition, laboratory accreditation has further advanced the goal of the establishing high quality standards for the provision of nuclear cardiology services. This article summarizes the principles of nuclear cardiology single photon emission computed tomography (SPECT) and positron emission tomography (PET) imaging and techniques for maintaining quality: from the calibration of imaging equipment to post processing techniques. It also will explore the quality considerations of newer technologies such as cadmium zinc telleride (CZT)-based SPECT systems and absolute blood flow measurement techniques using PET.
在过去的 40 年中，核医学在无创评估局部心肌血流和识别阻塞性冠状动脉疾病方面表现出色。这导致了在管理心脏病患者的诊断、风险分层和预后评估方面的进展。这些进展都基于高质量的核图像数据的收集。国家和国际专业协会已经为核实验室制定了指南，以维持高质量的核医学服务。此外，实验室认证进一步推进了为提供核医学服务制定高质量标准的目标。本文总结了核医学单光子发射计算机断层扫描（SPECT）和正电子发射断层扫描（PET）成像的原理和质量维护技术：从成像设备的校准到后处理技术。它还将探讨新的技术，如基于碲锌镉（CZT）的 SPECT 系统和使用 PET 进行绝对血流测量技术的质量考虑因素。
