Table 1. Agreement between Axial and Coronal Transcerebellar Diameter in 2D conventional and 3D reconstructed MRI.

MRI method	CCC	SE	95% Confidence Interval
2D conventional	0.989	0.0029	0.981 - 0.993
3D reconstructed	0.999	0.0004	0.998 - 0.999

CCC = concordance correlation coefficient. SE = standard error.

3D reconstructed MRI had higher CCC between axial and coronal transcerebellar diameters than 2D conventional MRI (Z score = 5.676, p<0.001). The p-value corresponds to the null hypothesis that CCC between axial and coronal measurements is the same in 2D conventional and 3D reconstructed MRI. Note that 3D reconstructed MRI had a smaller standard error than 2D conventional MRI, and the 95% confidence intervals do not overlap.
