In terms of diagnostic performance, the accuracy, specificity, and PPV of using FFR-CT to detect coronary stenosis were 81%, 79%, and 65%. These values were all significantly greater than those ...

Among the participants with normal CT-FFR results and a high coronary artery calcium score, the three-year adverse outcome rate was 2.2% (4/182).

LONDON, UK — The use of a diagnostic strategy with fractional flow reserve (FFR) derived from computed tomography (CT) significantly reduces the number of patients requiring invasive coronary ...

The overall benefit was even more significant for the CT-FFR group with only 21.9% requiring a surgical procedure to insert stents to open narrowed coronary arteries, compared with 78.9% of the ...

CT-FFR uses coronary CT angiography images of the heart, AI algorithms and computational fluid dynamics to simulate the amount of blood flowing through the coronary arteries.

In patients with critical limb ischemia, CT-derived fractional flow reserve often detected silent coronary ischemia, and selective revascularization of those diagnosed with it improved outcomes ...

Compared with coronary CTA interpretation alone, CT-derived fractional flow reserve yields higher diagnostic performance and differentiation of ischemia among patients and vessels with high ...

He added that given that there are fewer than 3,000 board-certified physician readers capable of interpreting coronary CT angiograms, Cleerly’s technology “now offers a unique opportunity to ...

CT coronary angiography for diagnosing coronary artery disease: ... The results of three studies show that both CT-FFR and CTP as an optional add-on to CCTA contribute to a less invasive ...

Patients with significant narrowing/blockages on coronary CTA who underwent CT-FFR had lower rates of invasive coronary angiography (25.5% vs. 74.5%) and subsequent percutaneous coronary ...

Insights into CT-derived Coronary Fractional Flow Reserve and Coronary Artery Calcification. Radiology , 2023; 308 (3) DOI: 10.1148/radiol.232150 Cite This Page : ...

During the study period, 3,098 patients underwent coronary CTA. Of these, 113 coronary bypass grafting patients were excluded. Of the remaining 2,985 patients, 292 (9.7%) were referred for CT-FFR ...
