Fig. 6From: The assessment of left ventricular volume and function in gated small animal 18F-FDG PET/CT imaging: a comparative study of three commercially available software toolsCorrelation and Bland–Altman analysis of ejection fraction (EF) showing bias and agreement. Scatter plots illustrate the correlation of EF among QGS, PMOD, and MIM. A PMOD vs QGS, B MIM vs QGS, and C MIM vs PMOD. A 95% confidence interval is plotted in grey color. Corresponding Bland–Altman-plot on the right side. Dotted lines display the limits of agreement (LoA; ± 1.96 SD) and biasBack to article page
