Correlation between FFR and step-up IBS.

, 2015
There was an inverse correlation between FFR and step-up IBS (r = −0.84; R2 = 0.71; P < 0.001). FFR, fractional flow reserve; IBS, intensity of blood speckle.

Comparison of systolic and diastolic CT-FFR for myocardial ischemia diagnosis

BMC Medical Imaging
Background CT-derived fractional flow reserve (CT-FFR) is a powerful tool for identifying hemodynamic ischemia. Coronary CT angiography (CCTA) images with the best quality in a cardiac cycle are conventionally reconstructed in clinical practice.
