Non-Invasive Flow Ratio (NiFR) Measurement based on Angiography Images
The NiFR (r = 0.738, P< 0.001) exhibited a strong correlation with pressure- wire-based FFR. The result indicated that FFR was higher than 0.8 in the arteries with non-significant stenosis and lower than 0.8 in the arteries with significant stenosis.
