FFRCT Is It Radiology or Cardiology Imaging ~ An example of FFRCT imaging from Beaumont Hospital in Royal Oak Mich The left image shows a 3D generated image of the coronary tree from a CT scan evaluated with computational fluid dynamics to determine the FFR numbers It shows a severe restriction of the left main artery which requires a stent to revacularize

FFRCT HeartFlow Coronary Artery TestLoyola Medicine ~ Noninvasive Technology for Coronary Artery Disease Fractional Flow Reserve – Computed Tomography FFRCT is a noninvasive technology developed by HeartFlow Inc to test for coronary artery disease HeartFlow® technology uses computed tomography CT scans to calculate how much blood is flowing through the coronary arteries

Clinical Use of CTDerived Fractional Flow Reserve in the ~ Results Among 555 patients 297 underwent coronary CTA and FFR CT 196 negative 101 positive whereas 258 had coronary CTA only The rejection rate for FFR CT was 16 At 90 days there was no difference in major adverse cardiac events including death nonfatal myocardial infarction and unexpected revascularization after the index visit between the coronary CTA and FFR CT groups 43 vs

Fractional flow reserve Radiology Reference Article ~ Fractional flow reserve FFR is a technique to evaluate the hemodynamic relevance of coronary artery stenoses 12 It is defined as the ratio of maximal flow achievable in the stenotic coronary artery to the maximal flow achievable in the same coronary artery if it was normal 1 Fractional flow reserve has become the gold standard method for assessing coronary lesion severity during

The MATCH Investigation CT Myocardial Perfusion and CT ~ The accuracy of detection of myocardial perfusion abnormalities will be compared between PETMPI and the combined CTMPI CTFFR approach Diagnostic accuracy using CTMPI and CTFFR will be calculated in sense of sensitivity and specificity and overall AUC with PET as the reference standard

Fractional Flow Reserve FFR PTCA ~ Fractional Flow Reserve or FFR is a guide wirebased procedure that can accurately measure blood pressure and flow through a specific part of the coronary artery FFR is done through a standard diagnostic catheter at the time of a coronary angiogram cardiac catheterization

CT Perfusion and FFRCT are Ready for Clinical Use ~ A growing body of evidence supports the use of functional computed tomography CT imaging including myocardial stress CT perfusion and CTderived fractional flow reserve FFRCT for guiding clinical management in appropriately selected patients with suspected ischemic heart disease
