November 2015 – The impact of image resolution on fractional flow reserve (FFR).

Shengxian Tu and his team have carried out an interesting study, whereby they compared two geometrical models of the same vessels, one by CTA and the other by 3D QCA. Image based FFR was computed using CFD simulations, applying the same hyperemic flow rate derived from the angio images at the inlet boundaries. They found a moderate agreement between FFRCTA and FFRQCA, and based on these observations suggest that image resolution has a significant impact on FFR computation.
