Recent advances in software and hardware for cardiac SPECT have the potential to revolutionize nuclear cardiology. It is easy to use these technologies to maintain the status quo and lower radiation dose, despite the fact there is very little evidence that lowering patient dose in already low dose imaging protocols confers any benefit to patients. Cardiac SPECT has tremendous potential for risk stratification, molecular tracers, and high temporal resolution management of patients with electrophysiological disorders. In addition, these new reconstruction techniques can offer spatial resolution that is comparable and sometimes even superior to PET. Lastly, recent research has also held out the potential for performing absolute blood flow qualification using SPECT instrumentation. As these new technologies become available, the goal should be to make images better and improve patient care first, then optimize the dose.
心脏 SPECT 的软件和硬件的最新进展有可能彻底改变核医学。尽管几乎没有证据表明在已经低剂量成像方案中降低患者剂量会给患者带来任何益处，但使用这些技术来维持现状和降低辐射剂量是很容易的。心脏 SPECT 在风险分层、分子示踪剂以及电生理障碍患者的高时间分辨率管理方面具有巨大潜力。此外，这些新的重建技术可以提供与 PET 相当甚至有时更优的空间分辨率。最后，最近的研究还为使用 SPECT 仪器进行绝对血流定性提供了可能性。随着这些新技术的出现，目标应该是首先使图像更好，改善患者护理，然后优化剂量。
