Cardiac QSM in Relation to Invasive Catheterization. a Scatter plot examining QSM derived ΔSaO2 in relation to invasive catheterization derived ΔSaO2. A good correlation (r = 0.87, p < 0.001) and linear relationship between the two approaches is observed. b Bland Altman plot. Note small bias between the two tests (−.1%) and moderate limits of agreement (±8.6%)
