Stress single photon emission computed tomographic (SPECT) myocardial perfusion imaging has enjoyed great success over the past several decades as the modality of choice for accurately diagnosing and risk stratifying patients with suspected or known coronary artery disease. Same-day low-dose rest/high-dose stress imaging protocols have generally been widely adopted for this purpose. However, recent studies indicate that rest imaging may be unnecessary in patients with a normal initial stress SPECT. Elimination of the additional imaging would decrease costs, streamline patient evaluations, and reduce radiation exposure. SPECT imaging guidelines should be revised to reflect this new information.
在过去几十年中，单光子发射计算机断层扫描（SPECT）心肌灌注成像作为一种准确诊断和分层疑似或已知冠心病患者风险的方法取得了巨大成功。为此，通常广泛采用同日低剂量静息/高剂量负荷成像方案。然而，最近的研究表明，对于初始负荷 SPECT 正常的患者，静息成像可能并非必需。消除额外的成像可以降低成本、简化患者评估并减少辐射暴露。SPECT 成像指南应进行修订以反映这一新信息。
