Measuring absolute myocardial blood flow (MBF) is becoming a common aid for diagnosing patients suspected to have coronary artery disease. An MBF study, however, requires a scanner with high count rate capability, is more susceptible to artifacts, and is much more technically involved than static imaging, which leads to a greater risk of artifactual results contaminating the final result. This technical note gives the reader an introductory understanding of the method for calculating MBF. It then describes the scanning protocol, potential pitfalls and how to recognize them, and quality control steps that should be taken to avoid basing a clinical decision on possibly inaccurate flow information.
测量绝对心肌血流量（MBF）正成为诊断疑似冠心病患者的常用辅助手段。然而，MBF 研究需要具有高计数率能力的扫描仪，更容易受到伪影的影响，并且比静态成像技术更复杂，这导致伪影结果污染最终结果的风险更大。本技术说明使读者对计算 MBF 的方法有初步的了解。然后描述了扫描方案、潜在的陷阱以及如何识别它们，以及应采取哪些质量控制步骤来避免基于可能不准确的流量信息做出临床决策。
