Comparison among structures and thickness measurements of μCT and histological images. Corresponding sagittal view of A) histology and B) μCT images of the same knee joint. C) Magnified view of inset in panel A, indicating bone (blue), HDM contrast agent (orange) and cartilage (light pink). D) Magnified view of inset area shown in panel B, indicating bone (gray color), HDM contrast agent (light gray) and cartilage (black). White arrows indicate the cartilage in all images. E) Pearson’s correlation coefficient between histology and μCT cartilage thickness was found R2=0.90 with a slope of 0.97.
