CT-derivedfractional flow reserve (CT-FFR) performed similarly overall but better than coronary CTA in direct comparison.Clinical relevance Addition of coronary CTA to TAVI planning-CT to screen for obstructive CAD could reduce negative invasive coronary angiographies in TAVI work-up. CT-FFR could ...
In patients with non–ST-segment elevation acute coronary syndrome (NSTEACS), coronary pathology may range from structurally normal vessels to severe coronary artery disease. Objectives The purpose of this study was to test if coronary computed tomography angiography (CTA) may be used to exclude cor...

The first part describes the clinical value of contrast-enhanced non-invasive CT coronary angiography, including the diagnostic accuracy of CT coronary angiography for the exclusion or detection of significant CAD with coronary artery stenoses that may require angioplastic intervention, as well as ...
Noninvasive diagnosis of ischemia-causing coronary stenosis using CT angiography: diagnostic value of transluminal attenuation gradient and fractional flow reserve computed from coronary CT angio- graphy compared to invasively measured fractional flow reserve. JACC Cardiovasc Imaging. 2012;5:1088-1096....
Angio-FFR and CT-FFR were measured in 110 patients (139 vessels) with stable coronary disease using invasive FFR as the reference standard. On per-patient basis, angio-FFR was highly correlated with FFR (r =0.78, p < 0.001), while the correlation was moderate between CT-FFR and FFR (r...
coronary CTA and the coronary plaque morphology estimated by CTA beyond coronary angiography including the comparison to Stress nuclear MPI using single-photon emission tomography. It hopes that an integrated, multi-modality imaging approach will become the gold standard for noninvasive evaluation of ...
