Fig. 7From: Two fully automated data-driven 3D whole-breast segmentation strategies in MRI for MR-based breast density using image registration and U-Net with a focus on reproducibilityA simulation illustrating the statistical significance of a small enhancement of BD measurement reliability. When the test-retest standard deviation is reduced from 1.42% to 1.11%, the p value decreases from 0.13 to < 0.05 (assume N = 10; true change = 1%)Back to article page
