Since the development of gated SPECT imaging approximately 10 y ago, this technique is now almost universally used as an adjunct for radionuclide perfusion imaging, enabling the assessment of perfusion along with determination of regional and global left ventricular function in the same examination. The gated SPECT determination of the left ventricular ejection fraction and volumes has been extensively validated. Additionally, this method allows for the improved identification of soft-tissue artifacts and enhances the detection of multivessel coronary artery disease. Furthermore, gated SPECT provides powerful information for the risk assessment of patients with known or suspected coronary artery disease and aids in the assessment of myocardial viability. Gated SPECT imaging has clearly become an integral part of radionuclide myocardial perfusion imaging.
自从大约10年前门控单光子发射计算机断层扫描（gated SPECT）成像技术发展以来，该技术如今几乎已被普遍用作放射性核素灌注成像的辅助手段，能够在同一次检查中评估灌注情况以及测定局部和整体左心室功能。门控SPECT对左心室射血分数和容积的测定已得到广泛验证。此外，这种方法有助于更好地识别软组织伪影，并提高对多支冠状动脉疾病的检测能力。此外，门控SPECT为已知或疑似冠状动脉疾病患者的风险评估提供了有力信息，并有助于评估心肌存活性。门控SPECT成像显然已成为放射性核素心肌灌注成像不可或缺的一部分。
