Evaluation of Regional Variability and Measurement Reproducibility of Intravoxel Incoherent Motion Diffusion Weighted Imaging Using a Cardiac Stationary Phase Based ECG Trigger Method

Figure 4

The Bland-Altman plots of ADC, PF, , and (from upper to bottom) in left hepatic lobe with FB IVIM-DWI (left) and CaspECG (right) IVIM-DWI. Blue line = mean absolute difference and red lines = 95% confidence interval of the mean difference (LOA). The CaspECG method showed higher reproducibility in all quantitative parameters than FB method with lower LOA.
