This study demonstrated that in a single center experience, effective radiation dose received by patients is higher when the combination of coronary computed tomographic angiography (CTA) and single‐photon emission computed tomography (SPECT) imaging were used together, than when a combination of a non‐invasive modality was coupled with an invasive modality (coronary angiography ± FFR). Although significant improvements in non‐invasive imaging have emerged to help further risk stratify patients with coronary artery disease, coronary angiography remains a powerful tool, and still appears to deliver a lower effective radiation dose when used to risk stratify patients appropriately. Further studies in dose reduction with nuclear imaging, coronary CTA, and virtual FFR are needed to reduce the dose of radiation and improve the diagnostic power of non‐invasive imaging.
