From: CMR validation of left ventricular volumes and ejection fraction measured by the IQ-SPECT system in patients with small heart size

Fig. 4

Bland‒Altman test for consistency of the left ventricular ejection fraction measured by SPECT with different reconstruction parameters and by cardiovascular magnetic resonance (CMR) in the normal group. The dashed line represents the mean of the difference (Xd). The three solid lines are the upper limit of agreement (LOA) of the difference (Xd + 1.96SD), zero, and the lower LOA of the difference (Xd − 1.96SD) from top to bottom, respectively. Xd mean of the difference, SD standard deviation of the difference
