Fig. 4From: Delineation of two intracranial areas and the perpendicular intracranial width is sufficient for intracranial volume estimationPearson correlations found during the validation step. The correlations with 95% confidence intervals for method (M) 1 are shown with an x marker, for method 2 with square markers, for method 3 with circle markers and for method 4 with plus sign markers. For each method, except for method 1, the correlations for coronal (Cor), sagittal (Sag) and transversal (Tra) intracranial areas are presented from left to right. The dashed line marks the y-coordinate for correlations of 0.99Back to article page
