Bland–Altman plots for the reproducibility of apparent diffusion coefficients (ADCs) values between the two observers’ measurements.

<p>The blue line indicates the absolute difference and the dotted red lines indicate the 95% confidence interval of the mean difference. The mean absolute difference in the ADC measurements between the two observers is 0.004 × 10⁻³ mm²/s (limit of agreement, 0.20–0.66).
