In a recently published study in patients with acute coronary syndrome (ACS) and concomitant moderate non-culprit lesions (NCLs), on-site CT angiography-derived fractional flow reserve (CT-FFR) was compared to conventional coronary angiography (CCTA), invasive fractional flow reserve (FFRi) and dobutamine stress echocardiography (DSE) in order to anatomically and functionally determine the occurrence of lesion-specific ischemia requiring revascularization by using a non-invasive method. Despite the limited usefulness of CT-FFR in the functional evaluation, the study reported a superior diagnostic performance compared to conventional CCTA in the anatomical assessment.
