Curation of automatic image segmentation can enhance accuracy of output metrics. Comparison of error with A, vessel length density (mm/mm²), C, vessel area fraction, E, vessel diameter (µm), and D, branchpoint count from automated analysis using default parameters before and after manual curation of image segmentation. Comparison of error with E, vessel length density, F, vessel area fraction, G, vessel diameter, and H, branchpoint count from automated analysis using degraded parameters before and after manual curation of image segmentation (for each of the two datasets, two‐tailed paired t tests with Bonferroni correction, 4 comparisons, α = 0.05, N = 36 images)
