From: Baseline correction of phase-contrast images in congenital cardiovascular magnetic resonance
Variable | Clinically Significant Change | Marked Change |
|---|---|---|
MPA or AAO flow | ≥ 0.5 L/min/m2 | ≥ 1.0 L/min/m2 |
RPA or LPA flow | ≥ 0.25 L/min/m2 | ≥ 0.5 L/min/m2 |
Q P /Q S | ≥ 0.4 | ≥ 0.8 |
Q P R fraction | =≥10% | ≥ 20% |
PR or AR fraction | ≥ 10% | ≥ 20% |
