With 3 Types of Respiratory Acquisition: 3.0 T Respiratory Triggered Acquisition Can Obtain Higher Quality DWI Images of the Upper Abdomen

Figure 2

TheBland–Altman plots of ADC for the normal liver parenchyma in breath-holding (BH), respiratory-triggered (RT), and free-breathing (FB) DWI. ((a)–(c)) The range of consistency limits of ADC values between two scans of breath-holding DWI; ((d)–(f)) the range of consistency limits of ADC values between two scans of respiratory-triggered DWI; ((g)–(i)) the range of consistency limits of ADC values between two scans of free-breathing DWI. The differences of ADC (y-axis) were plotted with the mean ADC measurement (x-axis) of each two acquisitions; a continuous line represented the mean absolute difference (mean bias), and dashed lines represented the 95% confidence interval of the average difference (limits of agreement). ADC values on the Y and X axes were ×10⁻³mm²/s.
