Assessment of collagen fiber orientation dispersion in articular cartilage by small-angle X-ray scattering and diffusion tensor imaging: Preliminary results

Measurements of the orientational dispersion of collagen fibers in articular cartilage were made using diffusion tensor imaging (DTI) and small-angle X-ray scattering (SAXS) on matched bovine articular cartilage samples. Thirteen pairs of samples were excised from bovine knee joints; each pair was taken from neighboring locations in the same bone. One sample from each pair was used for DTI measurements and the other for SAXS measurements. Fractional anisotropy (FA) values were calculated from the DTI data both for the individual imaging voxels and for whole regions of interest (ROI).
