Fig. 6From: CMR-based blood oximetry via multi-parametric estimation using multiple T2 measurementsBland Altman plots comparing CMR measurements of O2 saturation against reference O2 saturation by catheterization. The plots show the agreement between the CMR estimates of O2 saturation from the different solutions to the L-M model - a global calibration, b unconstrained optimization, c fixed nuisance parameter, and d constrained nuisance parameter - with the reference O2 saturation by catheter sampling. Note that the y-axis in plot (b) is on a different scaleBack to article page
