a) % area stenosis versus PC-MRI derived ΔP measurement. An exponential increase in ΔP was observed as % area stenosis increases. b) Pressure measurement comparison between ΔP calculated via NS-equations and Δ measured using pressure transducer. Excellent correlation (R2 = 0.938) was observed between the two techniques, validating the feasibility of PC-MRI derived ΔP.
