Scatterplot and Bland-Altman plot for the CC/IT ratio (n = 558). Scatterplot (A) and Bland-Altman plot (B) for the CC/IT ratio measured on NCCT and MR imaging. The Bland-Alman plot had a mean difference of 0.0002 (95% limits of agreement, −0.005–0.005). Highly concentrated areas could be observed, which can be seen in highly correlated measurements.
