Distribution and concentration of contrast agents. (A) 3D volume maps quantifying the stain distribution of iodine (top) and barium (bottom) in the soft tissue and blood vessels respectively within the double-stained mouse hindlimb. Some low concentrations regions (white arrow) with a systematic pattern of voxels are attributed to ring artefacts or general noise. (B) Histogram detailing the statistical breakdown of concentration distribution on a voxel-by-voxel basis for each chemical stain of the sample in (A). (C) Volume maps for the triple-stained mouse forelimb, showing absolute concentration values in each voxel for iodine (top), BaSO4 (middle) and PTA (bottom). (D) Concentration distribution histogram for each stain within the sample in (C).
