Abstract:We examined the effect of minimal lumen segmentation uncertainty on Fractional Flow Reserve obtained from Coronary Computed Tomography Angiography . A total of 14 patient‐specific coronary models with different stenosis locations and degrees of severity were enrolled in this study. The optimal segmented coronary lumens were disturbed using intra and inter‐operator variations on the segmentation threshold. was evaluated in each case by 3D‐OD CFD simulations. The findings suggest that the sensitivity of to t… Show more
