Representative images for invasive FFR and FFRCT measurements. A ICA image showing the tip of pressure-wire position in left anterior descending artery (LAD) during invasive FFR and the measured FFR was 0.78. B The corresponding pseudo-colorized FFRCT image show the site of target lesion and the measured FFRCT at 1, 2, 3 cm distal to the target lesion (FFRCT-1 cm, FFRCT-2 cm FFRCT-3 cm) and the lowest FFRCT (FFRCT-lowest). LAD, left anterior descending artery; FFR, fractional flow reserve; FFRCT, CT fractional flow reserve; FFRCT-1 cm, FFRCT measured at 1 cm distal to the lower border of the target lesion; FFRCT-2 cm, FFRCT measured at 2 cm distal to the lower border of the target lesion; FFRCT-3 cm, FFRCT measured at 3 cm distal to the lower border of the target lesion; FFRCT-lowest, lowest FFRCT value in the distal vessel tip
