Assessment of ventricular function (e.g., ejection fraction, wall motion, wall thickening) during myocardial perfusion single-photon emission computed tomography (SPECT) can serve as a cost-effective technique to provide more diagnostic data with fewer diagnostic tests. With the advent of 99mTc-labeled perfusion agents and advances in technology, myocardial perfusion studies can be augmented on a routine basis to provide additional diagnostic information on ventricular function by use of one gated SPECT acquisition. This technique has the potential to reduce health-care costs by reducing the number of unnecessary coronary angiographies that are now performed on patients with equivocal results of perfusion or incomplete risk stratification from standard myocardial perfusion SPECT.
在心肌灌注单光子发射计算机断层扫描（SPECT）期间评估心室功能（例如，射血分数、室壁运动、室壁增厚）可作为一种经济有效的技术，通过较少的诊断测试提供更多诊断数据。随着99mTc标记灌注剂的出现和技术进步，心肌灌注研究可以在常规基础上得到加强，通过一次门控SPECT采集提供关于心室功能的额外诊断信息。该技术有可能通过减少目前对灌注结果不明确或标准心肌灌注SPECT风险分层不完整的患者进行的不必要冠状动脉造影数量来降低医疗成本。
