Contrast-enhanced CT with a High-Affinity Cationic Contrast Agent for Imaging ex Vivo Bovine, Intact ex Vivo Rabbit, and in Vivo Rabbit Cartilage

The high affinity of a cationic iodinated contrast agent for cartilage provides better tissue visualization, easier segmentation, higher contrast-to-noise ratios, and longer usable imaging windows and requires a lower dose of injected contrast agent compared with an anionic contrast agent.
